Edward Felten recently lost his Internet account, claiming that his ISP cancelled it because of a single erroneous complaint filed by SpamCop about a mailing list posting that mentioned his new weblog.
Though his use of the term "Stalinist" to describe this is comically overblown, Felten has a legitimate beef about how a false accusation of spamming can harm a Web publisher. However, he doesn't name the party that's truly to blame -- his ISP, which should have enough experience with spam complaints at this point to be viewing them with a measure of skepticism. SpamCop is just a tool that makes it convenient for people to report and complain about spam. It doesn't force ISPs to be stupid.
