The question Win Server 2008 RDP Attack caught my eye as I was going through the bounty questions. To me it is clearly off topic, so I voted to close it as such... only to be told by the system that I couldn't:
To me this is a bug. If the question is migrated then the bounty can go with it. If it is closed then the bounty doesn't matter - the OP has already had it deducted (I wouldn't even care if they got it refunded). But when a question is off topic (or closeable for another reason) then placing a bounty on it shouldn't make it immune from the correct actions of the community.
Edit:
I've since flagged the question for mod attention. I think there is the possibility to change the flow for this, so that OT/NARQ questions can still be close voted and don't get the bounty refunded, but maybe the other close reasons are either disabled or the bounty poster gets a refund (as they can be either purely accidental (Exact Duplicate) or arguably more subjective (Not Constructive / Too Localized)). Or maybe I'm just over-thinking this and the bounty should get auto refunded.
