I guess if I had to vote right now right now, I'd go with Godot, if only because I don't believe his innocence and his doctor claim. However, since I don't have too much evidence to go on with that, I'm not going to vote for him. Yet.

Luke: Well, that too. But apparently it seems people would rather have inane posts than no posts. So I will adhere to their wishes.

Godot: Sure, you and Gant have the most posts by a large margin, but half of those were spam

EDIT: Bikini and Valant's numbers are kind of disheartening. Problem with suspecting inactives is not having much to go on other than a gut feeling, though.
