Yahoo Revives Pay-Per-Email, With Charitable Twist

holy_calamity writes "Yahoo research have started a private beta of a scheme that resurrects the idea of charging people to send email to cut spam. Centmail users pay $0.01 for each message they send, with the money going to a charity of their choice. The hope is that the feel good effect of donating to charity will reduce the perceived cost of paying for mail and encourage mass adoption, making it possible for mail filters to build in recognition of Centmail stamps."

How Exactly Does This Fight Spam?

[eldavojohn]

Subtitle of CentMail:

Do Good. Fight Spam.

So it sounds like an 'opt-in' program for doing otherwise would be suicide by a mail provider. And since it's opt-in, I highly doubt the spammers will be doing the opting. So unless your penny is going to an anti-spam organization, how are you fighting Spam?

Also, I'm not too clear on how this would work. Wouldn't it require a certificate-like central authentication server? And wouldn't this increase in traffic just exacerbate the situation of too much traffic? Especially if all Spam starts to come with fake 'stamps.'

The idea is that a Centmail signature attached to a message would automatically reduce the message's spam likelihood; if enough people adopt Centmail, then receivers would be increasingly able to require a Centmail signature on mail, and killfile mail that lacks such a signature.

In theory, great. In practice, I predict it spiraling out of control as different parties try to "get in on the action" and see a chance to turn a profit instead of just giving the money to charity.

Problem is this: if you blindly trust Centmail, then it'll be worth it for spammers to pay to send email. Don't believe it? Check your physical mailbox.

$10 for guaranteed delivery to 1,000 users?

Now here's something both the spammers and the ISP's will love. I presume somewhere in their long-term plan is a means of getting rid of all those pesky renegades who run their own email server and don't opt into this scam

Re:$10 for guaranteed delivery to 1,000 users?

[prograde]

From the paper, section 3.2 http://centmail.net/centmail.pdf :

A related scenario is when a user attempts to reuse a single legitimately obtained stamp to validate a single message sent to thousands of people. This is in fact considered to be acceptable behavior from the perspective of CentMail, similar to the use of blind carbon copy (bcc) for emails.

That sounds like exactly what spammers do - send the same message to thousands of people. So, really, that's $10 for delivery of 1,000 unique messages to unlimited millions of recipients. Good deal!

Oh well

Your post advocates a

( ) technical ( ) legislative ( ) market-based ( ) vigilante (x) charitable

approach to fighting spam. Your idea will not work. Here is why it won't work. (One or more of the following may apply to your particular idea, and it may have other flaws which used to vary from state to state before a bad federal law was passed.)

( ) Spammers can easily use it to harvest email addresses
(x) Mailing lists and other legitimate email uses would be affected
(x) No one will be able to find the guy or collect the money
( ) It is defenseless against brute force attacks
( ) It will stop spam for two weeks and then we'll be stuck with it
(x) Users of email will not put up with it
( ) Microsoft will not put up with it
( ) The police will not put up with it
(x) Requires too much cooperation from spammers
(x) Requires immediate total cooperation from everybody at once
( ) Many email users cannot afford to lose business or alienate potential employers
( ) Spammers don't care about invalid addresses in their lists
( ) Anyone could anonymously destroy anyone else's career or business

Specifically, your plan fails to account for

( ) Laws expressly prohibiting it
(x) Lack of centrally controlling authority for email
(x) Open relays in foreign countries
( ) Ease of searching tiny alphanumeric address space of all email addresses
( ) Asshats
( ) Jurisdictional problems
(x) Unpopularity of weird new taxes
( ) Public reluctance to accept weird new forms of money
( ) Huge existing software investment in SMTP
( ) Susceptibility of protocols other than SMTP to attack
(x) Willingness of users to install OS patches received by email
(x) Armies of worm riddled broadband-connected Windows boxes
( ) Eternal arms race involved in all filtering approaches
(x) Extreme profitability of spam
( ) Joe jobs and/or identity theft
( ) Technically illiterate politicians
( ) Extreme stupidity on the part of people who do business with spammers
(X) Dishonesty on the part of spammers themselves
( ) Bandwidth costs that are unaffected by client filtering
( ) Outlook

and the following philosophical objections may also apply:

( X ) Ideas similar to yours are easy to come up with, yet none have ever
been shown practical
( ) Any scheme based on opt-out is unacceptable
( ) SMTP headers should not be the subject of legislation
( ) Blacklists suck
( ) Whitelists suck
( ) We should be able to talk about Viagra without being censored
( ) Countermeasures should not involve wire fraud or credit card fraud
( ) Countermeasures should not involve sabotage of public networks
( ) Countermeasures must work if phased in gradually
(x) Sending email should be free
( ) Why should we have to trust you and your servers?
( ) Incompatiblity with open source or open source licenses
( ) Feel-good measures do nothing to solve the problem
( ) Temporary/one-time email addresses are cumbersome
( ) I don't want the government reading my email
(X) Killing them that way is not slow and painful enough Furthermore, this is what I think about you:
(X) Sorry dude, but I don't think it would work.
(X) This is a stupid idea, and you're a stupid person for suggesting it.
( ) Nice try, assh0le! I'm going to find out where you live and burn your house down!
