This is something that the devs simply do not care about. If they did, it'd be fixed.

People are arguing about burden of proof and not thinking it through. There is zero, zero reason for your character model to be clipped under the map.

A two strike system for this would *decimate* this problem instantly, but they don't care enough to roll out a flag system for it.

Strike one, your character model trips an under the map trigger and you are instantly disconnected and booted from the game for three hours.

Strike two, permanent ban.

Still, there will be people who will argue that's not fair to real players, as if you could somehow accidentally get yourself under there daily.
