If Google had implemented webmaster profiling he'd have risked all of his websites, however many he has, by being naughty on just one. Perhaps that's next?
I own more than one but you can count them on one hand. I'm not sure I'd like to worry about one site taking out the rest, it's too easy for a machine to get it wrong and the effects would be devastating, but for obvious cases like this one... is it time? (is it already happening?)
