New thoughs on Spam from Paul Graham
Paul Graham (of Bayesian Filtering fame) has two followups to his original Plan For Spam. The first, So Far, So Good, examines how Bayesian Filtering has fared against spammers working to get around it.
It’s about a year now since A Plan for Spam. So far, filters are winning. This article analyzes the tricks spammers have tried to beat them, and offers some suggestions for the future.
While the second, Filters that Fight Back, suggests the next step. In border line cases spidering spamvertised sites could lead to a more accurate spam/no spam classification, but if this sort of filter were to become widespread I’d be concerned about it becomming a means of DDoS’ing innocent bystanders (a bit like the Slashdot Effect).
Both make an exelent read.
