      Or better yet, you can walk the extra block to the place that was advertized and throw a mad hissy fit complete with top-of-the-lungs yelling and screaming (don't forget sailor cursing!) about how much you hate spam and how angry and pissed off you get when you get it sent to your phone. Make a habit out of it. They can't really expect to keep you out with tresspass laws since they are *specifically* targeting you with an invitation to come to thier store. (IANAL, but I don't see how you could invite somone over to you house and then arrest him for trespassing when he steps through the door. Correct me if I'm wrong.) If you, and all your friends, do this loud enough and long enough, perhaps within earshot of a news reporter on a slow news day, pretty soon there will be a huge stigma against spamming passersby.

      Amusing point (:-), but I think you have the key point.

      I think there hasn't been a big crackdown on email spam because most people see it as an annoyance - Joe Users perhaps 'do their email' in one sitting, and delete the spam there and then.

      I find that people tend to stop what they are doing to check their messages, because they tend to be significant, from family or friends.

      I can imagine a huge groundswell of anger about SMS spam, and it will only take one idiot causing a pile-up on the freeway whilst checking a spurious message for the media to pick up on this and label the spammers a new pariah.

      The big deal is that some of us pay for SMS on a 'per-message' basis. I'm a VoiceStream Wireless(major US Wireless provider) and I only receive 100 free messages per month. After that, it could start costing me lots of money to receive shit that I don't need.

      Even with a reasonably low spam rate of 3 per day, that pretty much takes care of all of my monthly messages. Seeing as I actually use SMS for my own needs, I could see spam costing me an extra 5-10$ month; at which point I'm gonna start sending out bills to spam senders.

    I understand that spam by SMS is already becoming a problem, in the UK some of my friends have responded to competitions (SMS your answer to...), not realising that in the VERY fine print they were selling their soul (and mobile phone number) to the SMS spam merchants.

    Spam by email is bad enough - but spam by mobile phone when you could be interrupted any time, any where without knowing if it's a critical SMS from work, or meaningless spam is an invasion of privacy.

    I'd like to see this new form of spam stamped on hard, and stamped on fast, before it gains even more of a foothold as "acceptable practice". Anyone receiving spam by SMS should do everything possible to report it, and ensure that the companies making use of this form of advertising are made aware that it is totaly unacceptable.

    I would imagine that spam text messages would be hard to report because many of the headers are removed because of space/storage restrictions. I think that the burden would lie pretty heavily on the providers. How far is too far, though? If you're asking your provider to log and/or prosecute spammers, they inherently *have* to sort through your personal messages. As I understand it now, most services just send the information directly to your phone without having to actually store it on their servers at all.

    It seems we have forgotten all about fax machines and the law that they prompted.

    Let's see. There is a law against sending unsolicited ads to your fax machine. This came about because it cost the recipient to recieve this unwanted crap - in paper, toner, etc.

    Our legislators, in their wisdom, determined that we shouldn't have to be subject to crap we don't want, especially when we had to pay for it.

    Ok, now to cut to the chase. Even if my Internet service is billed on a flat fee instead of by bandwith or connect time (in the US), it still costs me a cash outlay (some divided portion of my monthly ISP fee), to recieve spam. Not to mention the value of my time dealing with it. I know this has been mentioned many times before, but the message doesn't seem to be getting through to the lawmakers.

Considering the intent of the fax law, doesn't this cover this eventuality already?

If they won't pay me, I'll whip out my sandwich board and picket the damn place, or make myself as annoying as possible. Or maybe I should do all of the above...

    The email address for the Docomo cell phone that my company issued me was apparently in use before, and got in the hands of spammers and was included in an email database. I have gotten 46 (!!) spam emails to that phone in the past 5 hours and 20 minutes, all for i-Mode sex sites and such.

    At least in my case my company is picking up the bill-- i-Mode users in Japan pay for all received packets, so you are billed for all of the spam that you receive.

    Docomo has tried to stop the flow by allowing you to block email from specified domains, but of course that doesn't help things at all. I know several people who end up having to change their cell phone email address every few months because the email features of their phone become unusable due to the amount of spam they start to get. (The spammers get their email address when they register on i-Mode capable web sites, or if they have an easy-to-guess email address like tanaka@docomo.ne.jp)

    Up until last year or so you could usually send email to [cell phone #]@[cell phone provider].ne.jp, but the cell phone companies all had to discontinue that service because of the amount of spam that would be sent to all of their customers.

    Compared to what I'm getting to my work phone, the amount of spam I get to my email accounts is nothing... :-P

    Consumer Information Bureau
    Federal Communications Commision

    if you ask that appropriate legal action be taken, it works! Not only that, you can sue the people who send the faxes (not for a ton, but the maximum amt is well over the cost of printer cartridges and paper)

    Since this seems like a fairly equivalent situation, i.e the cost of the spam will definitely have a fair sized impact on your own bill (unlike standard telephone telemarkating and junk mail)... i would be surprised if things didn't work out the same way once complaints start flowing

    Mobile spam is going to take off in a massive way because its more direct than email since the majority of people carry their phone everywhere and respond as soon as it bleeps.

    In fact its such a big thing that even respected global players such as Logica (their software runs over 50% of the SMS gateways in the world) are getting involved according to this article in the Financial Times.

    In short getting people responding to SMS spam is unreliable because due to difficiencies in the GSM protocol you can only catch about one SMS reply to an advert every 5 seconds.

    Because of this, take up of bulk SMS advertisements (where people respond) is slow. But thanks to the boffins at Logica, they now have software which can harvest 1,000 replies a second.

    Which suddenly makes pumping out SMS spam look a lot more worthwhile.
