Well, the main theory I thought I covered in my post for what they're doing is basically getting mad with folks that downvote them and trying to impersonate them. If it's steamcleaners and abuse reports that are flagging this group/individual, then they're probably not doing things they should do, either, to start with, which makes their retaliating against anyone and everyone more evidence of their bad behavior.

The other thought is, either on purpose or unintentionally, they are drawing attention to a good reason why there shouldn't be any incentives for flagging, like some people want, since right now you lose some voting power every time you do it.

Regardless, it's tough to do things like this without having some means to broadcast your grievances to the affected, because if you're hoping for some action, you're going to get ignored. It would be like terrorists doing something that mildly irritated people but it was so mild that those hit weren't that affected, and then the terrorists tried to announce their demands via fax. :)
