no more then one mod to undo at a time

I have been on Flockdraw/Drawplanet long enough to realize busy rooms such as "Planet" get trolled often.
As a result to the trolling, Active board moderators undo and ban/kick to revive peoples art and to stop the trolls doing this again.
Although, i and a few others have noticed moderators tend to undo all at the same time which causes unnecessary undoing and a lot of lag for the users.
i think it would be beneficial to make it that no more than one mod can undo at a time. this prevents lag and unnecessary undo's
