Killing Unwanted Text Messages from Yahoo! Alerts?
Creighti asks: "When I first got my new cellphone I immediately received several automated Text Message 'Alerts' from Yahoo and MSN which recurred on a daily basis. My guess was (is) that the previous owner of my cell phone number signed up for these things. Six months later I'm still getting unwanted text messages from Yahoo! Alerts.
I managed to get rid of the MSN messages by signing up with MSN (gack), registering the phone number as mine, and de-selecting all text messages. I've tried the same trick with Yahoo. I've tried filling out the Yahoo! Help form that appeared to apply (interestingly enough, the Yahoo Help entry I've used several times to request they stop sending the unwanted alert appears to have been removed, but clicking the 'No' button on this page would work). I've even tried emailing abuse@yahoo.com. Anyone else getting text-message spammed by Yahoo! (or any other service)? Any suggestions for what I should do next to try and get Yahoo! to stop sending these unwanted messages?" Why aren't the text message preferences deleted when the cancellation notices comes thru?
Send them a bill. They are using your airtime, with something you didn't ask for. If they don't want to pay the bill, they will find a way to stop it.

I suggest that instead of continuing to try to get Yahoo to stop sending the messages you instead contact your telephone company and ask them to block the messages before they get to your phone.
As they are making money off you and Yahoo isn't, you are more likely to get a useful response.
I didn't think of that...I feel sorry for the owners of my last 3 cellphone numbers.
Get them to block the originating #, or get them to change yours.
Because these alerts are like a mailing list subscription and the phone number is like an email address. The problem is phone numbers are reused, where email addresses, generally, are not.
Yahoo or MSN do not receive notification when someone cancels their phone account.
Yahoo! Mobile Devices, log in under your Yahoo account and select "Add a New Device", then add your phone number, or e-mail for the cell phone, depending on what your operator supports and then specifically do not choose any alerts.
Just a guess, but probably what is registered is an e-mail address like 3215551212@sprintpcs.com which is how e-mail can find its way to SprintPCS phones. The service you sign up for may have no relation to your cell provider, so cancelling one doesn't cancel the other and then your phone number (and hence e-mail address) can be recycled.
Ok, not about cell phone text, but about getting Yahoo to stop things...
I have an *ancient* Geocities home page, that was set up before Yahoo acquired them. I am "yoderm" on Yahoo and was on Geocities before the acquisition. Unfortunately, the GC home page is not associated with my Yahoo account. I now have no way of logging into the thing, and really want it deleted.
I've sent two messages through their "help" center, but no response. I've tried every support@ and help@ type e-mail I could think of for yahoo.com, geocities.com, and yahoo-inc.com. They all either bounce or get an automated reply that says "go to the help center".
Conclusion: Yahoo goes WAY out of their way to avoid dealing with human "customers".
Go through your local fast food drive-thru, order a coffee and make sure you spill it on yourself as you are reading your messages. I'm pretty sure the warning labels on the coffee do not yet include: Warning! Do not drink while reading text messages.
honest honey, all the porno text ads are from the previous owner of the cell phone.
Sneakemail and other aliasing services can be used to avoid this as well. Instead of sending the mail to 5551234567@sms.phoneprovider.com you can send it to a sneakemail address which will bounce it to your SMS. This way you can kill off the sneakemail address if necessary and stop the spam easily.
I've found that Yahoo's support for free services really really sucks. I can see why, but I'm starting to doubt any support even exists for these services. Good luck, though I think you are screwed.

Why aren't the text message preferences deleted when the cancellation notices comes thru?
Yahoo essentially knows nothing about the phone number. All it knows is that there is a number (or more abstractly, an email address) through which it should send its junk. They don't know who/what/where otherwise. They know nothing about who currently owns which phone #.
...how easy is it to dick with people you don't like by registering their cell phone number with dozens of text alert sites? If these messages don't include a way to unsubscribe, they probably aren't confirmed opt-in either.
is 'circulation' - the reason those morons are so keen on keeping people on their 'hit' list is so they can go to their paying clients and say, "Look! You're message is reaching 250,000 potential customers". The more 'circulation' or ratings a paper, magazine or program has, the more they can charge for it. Nevermind the fact that 249,997 people have just associated $PRODUCT with annoying marketing tactics.

I have a cellphone with Verizon (and an associated vtext account for messages.) I tried signing up for weather alerts on my cellphone but found out quickly that the messages sent were too long to be useful.
I was able to unsubscribe from the alerts - but even after I unsubscribed from the alerts, I kept receiving advertisements from the service sent to my cellphone.
After a couple of unsucessful attempts to get it stopped I finally poked around on the Vtext site and found out that I was able to block a specified domain from sending to my cellphone.
Blocking the domain of the weather alerts provider killed the spam as well.
See if your provider doesn't let you filter out @yahoo.com messages.

I have the same problem with my watch. It was receiving messages before i signed up for the paging service and still gets them after i've signed up and have configured it under Yahoo! Alerts. My guess is that Yahoo has a separate ID for the watch and does not know that it should be associated with the phone number that skytel gave me.
The difference between Canada and the USA is that in Canada healthcare is a right and gun ownership is a privilege.
But that's not the point here. Even if you don't pay extra to receive spam, you still don't want it. Since he doesn't want these alerts, to him, they're spam.
5 years ago, it was computer email spam. Today it's cell-phone spam. Who knows what it'll be in 5 years, or what the costs will be? Especially since some spammers are trying blocks of cell phone numbers.

Some idiot signed up for a passport account and gave them a dummy e-mail address that he just made up. Unfortunately it happens to be for a mailbox that I've used for years. The MS "welcome to .NEt passport" letter doesn't even give you an
option to tell them that this address was subscribed in error and to take ou off their lists. I've tried sending e-mails to addresses of real people there, but everything has been ignored. I continue to get crap from them as a result of this bogus sign-up, and can't get rid of them.
I'm an American. I love this country and the freedoms that we used to have.
And he's not a dumbass, either. He's found his choices are (1) put up with the messages, (2) change phone numbers, or (3) disable text messaging (carrier phenomenon). 1 and 3 are free, 2 costs money (albeit not much).
Why (4) get Yahoo! to! stop! it! please! isn't an option boils down to "they don't listen". It's one of those scary companies where there's no apparent way to actually *contact* anyone who can do something about this. There's no there, there so to speak.
He has said that the wireless carrier was particularly unhelpful, which doesn't surprise me. I had a problem for a while when I got my first cellular with getting FAX calls. They offered to *sell* me caller ID (an expensive option on a limited range of AMPS equipment), but wouldn't do anything about tracking down who it was.
I'm frankly surprised that there isn't more phone spam (how hard is it to figure out that all of a carrier's cell numbers are in NXX-5xx-xxxx?) or that message services don't build in a failsafe way to stop them, like adding a user-specfic hash code to every message and then have a web page where you can go, enter that hash, and disable that phone number's messaging.
This doesn't neccesarily apply to this exact situation, but it is related. I use SprintPCS. The SMS address that I am given is (for instance) 1234567890@messaging.sprintpcs.com. That's also my phone number. I think to myself, "I don't neccesarily want people who might SMS me to have my phone number, and I don't neccesarily want people who have my phone number to be able to SMS me." So my solution was to use my domain name (hosted by yahoo :O)) to make an email forwarder, Jared.2600@reack.com forwards to the 1234567890@messaging.sprintpcs.com. First, it's easier to remember. Second, I control it. If I start getting spam or unwanted messages, I can forward that email address to oblivion and make a new one. Also, if I do sign up for some sort of notification service, I can create a whole new forwarding address. Yahoo happens to offer unlimited email forwards with their domain name service, so I take advantage of that. I think most other domain hosts will do the same.
Why aren't the text message preferences deleted when the cancellation notices comes thru?
Simple, those notification messages aren't in any way related to that phone. A user is unlikely to cancel his/her yahoo account just because they cancelled their phone service.
It's obviously a problem, but definitely not an intentional one on Yahoo's part. An article like this on Slashdot is probably enough to get them to put up a page explaining how to get your number off someone else's account.
If the called party is charged for the call they may have run afoul of the Telephone Consumer Protection Act of 1991 (47 USC 227 and the rules under 47 CFR 64.1200). If so you can sue them for up to $1,500 for each "call" just like a junk fax.
That is complete BS but the same thing happened to me with email.
This is the problem.
1. Sign up for yahoo email.
2. Register an alternate email address of someone you don't like.
3. sign up the alternate address for all kinds of junk.
Their is no way they can cancel it. Yahoo will do what they always do when you email them for help, flush it down the toilet, or threaten YOU for spamming them...
I agree with some of the other posts here. You'll likely have to take this up with the phone service provider, NOT Yahoo!. I suppose if I just got the phone number, I'd demand a new one. I realize that this isn't always possible or ideal, but it's the sure way to get away from it all.
I've seen similar things happen to folks who sign up with larger ISPs. Recently one signed up with RCN, got an "available" e-mail address, connected for the first time only to find 50+ spams inside from various companies.
I think we're doomed to see this more and more as ISPs/phoneservice providers run out of name/numberspace. Recycling will happen. What can the providers do if the e-mail/phonemail address is out there already? Even if they close the number of X number of months, the spammers will still pump out ads at the address.

...I keep getting RH Network alerts in my e-mail inbox even though I no longer use RedHat. I've tried to unsubscribe on the RedHat site but it keeps resetting my preferences to "send e-mail to...". I've tried asking politely to have redhat support to remove my e-mail address from their list and/or kill the RHN account. I've threatened them with lawsuits under anti-spam laws (by the way, I knew this would not work if they called my bluff. I had no intention of pursuing legal action, I had only hoped that the possibility of legal action might get someone's attntion). Nothing, nada, zip. I keep getting their alerts and I can't get off the list no matter how hard I try. Why don't poeple think about these things when they design their systems?
What if you get a ruling in your favor, and they just decide to ignore it? How do you collect your money?

I had an old geocities account that didn't get converted to my yahoo account, and after months of unsuccessful attempts to get the darn thing cancelled, I wrote a letter to the Yahoo person in charge of copyright violations, and explained that Yahoo was violating my copyright to the works posted on that old geocities account. Effectively, by limiting my ability to control the distribution of my copyrighted works, they were violating my copyrights. Not that I wanted to sue or anything, I just wanted those pages gone.
Not long after, that account disappeared, and I was happy.
Unless you can config your phone to ONLY accept incoming messages forwarded via sneakemail, this won't help the user one bit - This spam will simply bypass the sneakemail account and go right to his phone.
Yes, it's a useful way to give out an SMS contact address without giving out your phone's direct address, which you can revoke if it starts receiving spam. But once spam starts coming directly to the phone, you're screwed.
And it's not the user's fault in this case - He didn't do anything to sign up for these spams, it happens that he has inherited the spam that a former user (to whom it was likely not spam) had.

Yes you can sue anyone for not paying a bill.

That's what I set up at work. We have those same type of numbers -- 5555551212@mobile.att.net -- so we just set up email aliases on our mail server, so when someone sends a mail to "page-soandso@domain.com" it goes to their pager. Very useful, and if a phone ever starts getting spam, we just change the email address or remove it. Makes it so we can recycle our phones to new people easily.
:)
You can even do this easily at home using any standard mailer and a mail alias file. Just point a domain at your home DSL link (or whatever you use), and put the entry into your "aliases" file. Even if you use Fetchmail to retrieve mail from a remote account, you can make it so that those remote accounts can eventually go to a pager address. Fun fun fun

What the hell would that accomplish? The spam is being sent to a phone number, which is tied to the SIM card. You can swap phones a hundred times but those SMS messages will follow you as long as your phone doesn't change.
Nahh.. I've got a nice new phone from Telus which supports 1X, SMS, two-way text messaging and all the other cruft; but I didn't get it because of that, I got it despite all of those features. I couldn't care less about surfing the WWW or reading e-mail on this small screen (small for a computing device, large for a cellphone). I got the phone because it was inexpensive and came with four months' of free airtime and an additional $100 credit towards my bill for a very low rate ($129.99 plus tax) and free activation. When I activated the phone, I simply told the girl not to add any web/text features - period. If I do decide later down the road that I want (some of) them I'll have the option. I like having choice, and eliminating all the phones that are web, 1X, or text-message ready severely reduces my choice (to almost nothing; most new digital phones nowadays are capable of all these features)

Spam is annoying in your inbox, when it makes it to your phone it is ten times the annoyance. Shouldn't they mandate a block/allow list for cellphones, since (on many plans) it's a pay-per service. i.e. with my local carrier, it's $0.10 for text message unless you subscribe to the service.
More recently, they allowed users to be exempt from either the service subscription or the per-use payments... but it's still annoying to have so little control over your phone email - especially once spammers decide to start hitting random 1235555555@text.mycellphoneprovider.com
Depending on where you live, you may be able to sue to recoup airtime costs. For example, California has passed an anti-mobile-spam law.
Unfortunately, unless you're bored and otherwise unemployed, this is hardly worth the while.
But what is this doing on the front page? This is something you ask a smaller specialized forum, not the slashdot community. I can hardly see how this will generate meaningful or intellectual discussion, and I can definitely not see how this is news for nerds or stuff that matters.

I use the Yahoo text messaging for once a month reminders (give dog meds, hair cut, wife ovulating,etc..) I'm not sure you can create a yahoo account to discontinue the messages since the messages are probably created by your cell number's predecessor's Yahoo account.
Does Yahoo even have access to this kind of information? "Yeah, can you guys look up my cell phone number among your thousands of subscribers and modify that subscribers text messenging preferences?" That sounds like a nightmare of a problem.
I suggest changing your Cell Phone number. That's your easiest solution.

A few years ago (not sure what I was thinking) I registered for a Yahoo! account. Of course, I wouldn't tell the scumbags my real DOB or zip code. Later I forgot about this account.
A few months ago Yahoo changed their spam policy to opt-out. Suddenly I started getting junk mail in my regular account. I tried to login to the Yahoo account to change the settings but couldn't since I forgot my password. I couldn't use the online thing to get a new password since it required my DOB and zip code to do that.
After several attempts at trying to sort it out with Yahoos customer disservice, I arrived at the following conclusions:
- I could not change the spam policy without signing in.
- They would not stop sending me junk mail to my regular email account without signing in.
- They would not delete the account unless I could prove it was me - having the same name and access to the email account registered for the account did not count.
- They would not give me the password to my account or change it.
I ended up just dumping the email account and starting afresh. Luckily, it was not one I used heavily.

I routinely handle complaints on behalf of my customers with their vendors. Some vendors, such as Verio, are beyond awful to work with based on my experience. Some vendors know me by name if enough of my clients have issues with them :-). I will outline my techniques for the common benefit of the readers.
My typical procedure (first week):
1. Contact first level personnel for about 3 days and gather employee IDs and case numbers.
2. Cease talking with first level and skip directly to first level supervisors confronting them with evidence. Do so for 1 day, on the 3rd day with at least 2 calls documenting the supervisor employee ID and case numbers.
3. Cease talking with supervisors and skip directly to second level supervisors. Do so for 1 day similar to 1st level.
4. Advise the second level supervisor that if the problem is not handled within the next 24 hours (the 5th day), the next directive will be received from his manager, ignore the laughter if any insues.
5. Follow up the next day (by then you should have a direct line) and remind him that the problem still exists.
Begin corporate level follow ups as follows (second week, generally 2 to 3 days):
1. Look up the company's corporate records for the following:
a) The front desk phone number
b) The Investor Relations (or any other PR function) - optional, never used it
c) The legal counsel of the company - optional, never used it
d) The company's mailing address for the HQ
2. Contact the front desk and ask to be transferred to the Office of the President/CEO. It's really none of their business to know why, but be candid and polite.
3. Believe it or not, most of the time you will in fact reach the executive assistant or someone whose job is specifically to resolve stretched out problems. Once you reach that person, obtain their direct number, e-mail, fax, and mailing address. Be prepared to send a ton of evidence of wrongdoing. The people at the top generally will have the organization chart available and know the executive in charge of that particular part of the company.
4. If you are lucky, and most of the time you won't be, you'll be given contact information for that particular executive. The executives are extremely busy people, so you'll likely talk to his assistant instead. Most of the time, however, it's not really necessary.
5. Be prepared for very different treatment the next time you call the customer service department as your name will be quite well known around the company. A simple memo from about 4-5 management levels down advising on how to deal with your problem carries infinitely more weight than any insult you can come up with.
Yes, I get results fast and this kind of work generally costs the client about $1200 or so. In fact, I once got a Nortel Regional VP in charge of my area to contact me within literally 40 minutes of me reaching just the front desk at Nortel to resolve a vendor issue. The vendor subsequently lost their authorization from Nortel.
Does this sound like overkill? Try to call Yahoo front desk, ask for Office of CEO, and present your case. Internal pressure is very effective.
Oh yeah, the mailing address is for the thank you letter along with hard copies of the evidence.
Enjoy!

If your phone service is with Verizon then go to http://www.vtext.com and under personalization there is a tab for message blocking in which you can block either a specific address or an entire domain.
I have a cell phone number that must have *just* been reassigned, because I am still getting a ton of calls from numbers that I have no idea who they are. I called a few of them back at the beginning to bitch at the people who were calling "my" number...but most caller IDs were the operator level number of some companies that must have been in contact with the person who previously had my phone...and those operators were WHOLLY unsympathetic.
So, how do I get this to stop? I have a call screening function, but it uses a minute of my airtime to pick up the phone and tell them it's not the old person's number anymore. If I turn it over to my voicemail, I have to wait and see if it was someone important (at a number i didn't recognize) and if they left me a message.
Any ideas?

A bank (Nation's Bank I think) called my cell phone one time. They claimed they "must have been given a wrong number" but the lady knew my name, so I wasn't buying it. I have no accounts with them, nor have I ever given out my cell to any companies. So I asked to speak with her manager. I happily told them that it was illegal to solicit to cell phones. They tried to feed me some more BS, so I asked for her manager. I finally got to someone decently high up, and they must have just been too busy to care, because they just said "send us a bill."
So, I itemized the lost minutes, as well as about an hour's worth of lost wages (this was during work) and sent it off. Sure enough, about two weeks later I got a check in the mail.
Needless to say, I didn't cash it...it makes a good story. Plus, my coworkers thought I was crazy when I was on the phone.
