I don't think anyone should get compensation, as it was an exploit. Although i do think OOO should really do a rollback, regardless of if they banned the guy who did it, tons of those crowns are still out there, illegitimate crowns that shouldn't exist. " but our logs show that the bulk of the resulting crowns have already been sunk via Punch. " is not an excuse to say a rollback isn't needed, in fact it is even more of a reason IMO, because now they can't just delete the crowns, they have been converted to UVs. You may argue that they have effectively been deleted already because of said sinking, but "a bulk" of the crowns is not ALL of the crowns, possibly hundreds of millions or even billions, which is no small amount.
