On our server, we wound up with players farming zones I didn't realize were revamped for the drops that were there. This obviously presented a problem.
We use a translocating NPC for people to get around. I set a proximity for him of 50 units. Then I set an enter proximity script like this:
	Code:
	sub EVENT_ENTER {
  if ($name ne /Greenmist/){
    $client->NukeItem(XXXXX);
  }
}
 There was a whole list. Anyone but me would have those items nuked from their person with no fanfare or even a message. It would work just as well under other sub EVENT types so long as you have a method for triggering it.
Hope this helps =)
