In reply to Paul Phillips - UKC and UKH:
So basically if I were to vote, I'd be flagged in a day or so. Considering, I'm not keen enough to vote middle of the pack pics. I generally only vote Bestest ever or Rubbish (well, to be honest, I haven't voted Rubbish, since when I still bothered to vote, it wasn't an option).
I agree with Durran in the sense that the voting should only be on the positive side... Sure, you still might get voters that only vote high, but odds are that they would not vote all that many pics per day (I wouldn't have the time).
Oh, and if hard pressed for the Rubbish kind of votes, how about Report Offensive (unless you already have one?), meaning mods would have to re-check it. Though, a simple button would not suffice but a proper explanation would also be needed...
