I feel very sad today when I read on slashdot that two anti-spammer services are shutting down due to massive distributed denial of service (DDoS) attack on their services. Monkeys.com and Compu.net joins Osirusoft in the antispam blacklists’ graveyard…ahem.

Strictly speaking, blacklists aren’t useful in stopping spams due to its high false-positive. Blacklists, is at best, a political tool to force ISPs to do the right thing to terminate spammers within their network.

While I don’t agree that blacklist is the best way to fight spammers, it is nevertheless a sad day to see spammers winning this war…
