Well, we are making an upvote and then unvote. It costs us the full vote. It just removes the payout from the abuser.

Would we refund it would only hurt us and not the abusers themselves. In a perfect world we spot all abuse before they use our service or review all votes by a human in under a minute, but reality is different.

We don't plan to punish normal users or something. Unvotes are a drastic measure and we will try to educate and warn users before we do that.
