This one spammer has created more than 5900 splogs in Blogger. All of splogs have multiple AdSense ads and a Google search. They are nothing more than an RSS feed dumped into Blogger with absolutely no original content. Here are the first twenty splogs as a sample.
UPDATE (2/22/06 7:10pm): Google does it again! This spammer's AdSense account is toast. I'll keep posting AdSense spammers and hopefully Google keeps doing what they do. I have couple more hard core AdSense spammers as well as this one truely "pro" spammer with nearly 900 domains registered to his name supported by multiple AdSense accounts. That one is going to take some effort to dissect.
UPDATE (2/28/2006 11:19pm) - Here is the complete list of 5905 splogs.
