There were some arrests for criminal spamming late last year in Russia, and that country is now the focus in the fight against spam, according to Richard Cox, CIO of the anti-spam group Spamhaus. He applauded the joint U.S.-China effort.

"The majority of the criminal spammers have already moved their activities from China to Russia," Cox said in an e-mail interview. "There is still a lot of work to be done in solving the problems of corruption and lawlessness in Russia that make it the international leader in spam and cybercrime."
