Thanks for the replies, guys. And I accept 0 reviews as long as they have better reason than just "Bush makes it suck". In fact, I accept 0 reviews even if there is no reason behind it, but I don't want to be bombarded by the same guy who is breaking the rules.
The thing is, n the space of one-two days, it received two reviews giving it a 0 due an animation of Bush. I suspected the two users were both the same person but I didn't care of it enough to contact someone. But now another review from a user who has hardly done anything on Newgrounds saying he doesn't like it (or much) for the exact same reason... I just want to shut this down in case this becomes a regularly activity by this person. That is IF it is the same person and it's not just different people following someone else.
