I have a program called Spam Hater, which sends nastygrams to spammers and their service providers, but most of the messages it generates bounce right back to me. Spammers typically forge the headers in their e-mail so the true sending address cannot be determined. Spam Hater will only be effective against newbie spammers who don't know how to cover their tracks. Spamford is suing his ex-provider, and even if he loses, it won't be long before another ISP gives him a new home. The spammers are running wild and there are no laws on the horizon to stop them.
Some people prefer to install spam filters in their e-mail program.
If you use AOL, you're at the mercy of their Mail Controls, which can filter certain spammer domains, but still misses quite a bit. As a geek and fan of non-intrusive government, I think a technical solution to the spam problem is preferable to a legislative one. But for now we'll have to keep hammering that Delete key.
