I came across this wonderful page today. It approaches the issue of stopping spam in a
very different way, by targeting the spammers and destroying their profit
rather than blocking their emails.
SpamVampire is a great idea, sucking the spammers bandwidth to the point
that its costing them more than they makeThis must be effective as the
spammers have gone so far as to give death threats to the creator! This phone transcript
was particularly amusing!
