Now I don't want to point fingers or anything... but there does seem like there's some vote cheating going on. I posted a pic (http://e621.net/post/show/186014) up last night and I noticed it was going well on votes and had quite a few faves on it. But then some other pic (http://e621.net/post/show/186019/) came up out of no where in less than 4 or 5 minutes with 16 votes and hardly any faves on it and that the pic I posted went from about 12 votes to only 4. You might want to think about changing the way the popularity of a pic is done with faves vs the voting system perhaps and that way you also know who faved it rather than the anonymous vote. But that's just my opinion.
