Google Inc.’s free BlogSpot service has become a happy hunting ground for spammers cashing in on the easy integration of AdSense advertisements into the “push-button” publishing tool.

An automated spam blog (splog) attack over the weekend was first flagged by Lockergnome’s Chris Pirillo, who accused Google of hosting a “crapfarm” of fake blogs.
