but what is the solution.
Drop "force pop" item from mobs in dungeon (NM or else), then pop it outdoor, if you wipe, NM wont disapear at all, it's open to everyone to claim it after that or not, it can last all day long until a group kill it.

In that way, only pos-hack bot could be annoying, but it's probably easy to find out who used it.

And a group that can't handle it, can give up, and NM will be free to claim, as no one want to spend time to see if a group fail, there'll be no much worries of bot claiming.
