Anti-SPAM

Doesn't really have much to do with IP, but I've been innundated with SPAM recently, and it's on my mind. N.B. this idea would never work; it relies on thoughtful self-interest on the part of spammers, which is unlikely. If even a small percentage of all spammers didn't do so, then spam would increase, not decrease. At any rate, the idea is you create a national registry of e-mail addresses, where every spammer can go to find people to spam. Then, when the spam is sent, if someone buys or even clicks on it, the spammer registers this in the directory. After a good number of spams (let's say anywhere from 15-50, people get the picture that this person is in no way going to buy anything from spam, and leave him/her alone. A few other problems with the idea include that spammers have no incentive to publicize a successful hit--it will only invite their competition to saturate the client, and that from their perspective it makes it less likely for someone to click on their link, since they know if they do the word will get passed on. But it was a nice thought.
