Moderators can refund bounties. We have a few powers that aren't widely advertised because they're things that need doing but we don't want every person who didn't get an answer crying foul.
A refund will usually only be given to keep things fair but it's completely up to the discretion of the moderator. Not getting an answer after 7 days is not a decent enough reason in most cases (so don't bother us about it).
