Since Zaitcev's posting atai lost his Master cert, as a result of a new Apprentice cert. atai responded by removing hjclub's Journeyer certification. I didn't see which order the events happened in, but the spammer and hjclub have both been deleted, probably marked as spam and deleted by other users as soon as they lost their certs.

That might be unfair to hjclub, but the community's response to spammers, and anyone who helps them, is pretty clear. Simple as it is, the self-policing system worked to defeat spammers again. 8191 is right that it would struggle if the spammers weren't utterly incompetent, but so far that hasn't been a problem. Maybe the intersection of SEO spammers and people with half a brain is an empty set?
