Test Update 06/11/2019 - Patch Notes and Discussions

It's not supposed to stop griefing, it's to stop kill stealers from stealing and looting the mob or more to the point, give them no reason to. So if some one does charm gate loot wipe your mob, there is no confusion over it being griefing and reportable vs contested battle over the mob.

Wouldn't be hard to program logging of who the charm owner was and what was loot wiped.
Could even send a message to the people on the mobs hate list for transparency and reportability.
