un-vote vudu
Maxi had no reason to suspect Mop it up, other than the fact that she hasn't been participating. I've checked that out, and the fact is, normally Mop it up posts early in the morning after new days have started, and late at night, near the end of the day. With the days starting around or even after noon, it's clear why we've seen less participation from her than one might expect: She's not around to make half the posts she normally does.
On the other hand, vudu couldn't control himself or his temper because of Maxi's decision to out he was a monster. Normally, I believe vudu would be reasonably upset at the matter, but had he been on the townie's side, I think he would have let the events pass a little easier. I think vudu may be one of the first real baddies in the game, Zedd or Rita.
Going on Maxi's suggestion, when he was focused purely on saving himself, seems like a bad idea to me. I think he was in a panic and voted for someone he'd seen votes go for before, hoping to start something against them to save himself, plain and simple.
