Why would that be suspicious? They could quite simply be taking the last game into account and voting through that.
In fact, that's encouraged.
Everything you can possibly do in this game, someone can think is "suspicious". Vote early, late.. Post a lot, don't.. you can't really win when it comes to that.
Except a lot of people made points to not vote based on the last game. There were posts earlier in this thread of people saying that and reasoning their thoughts based on only this game.
