I agree here, I've also thought about it before and don't care for making some dubious hacked exchange account rich, especially while they contribute nothing and do not engage at all with the community. We'll have to see about what kind of a solution would make sense, maybe a vote perhaps. It's good to have this discussion.
One approach is to edit the UTXO to exclude the offending addy and reassign the balance to a community-owned multi-sig address for use thereafter as a community Treasury.
