Yeah, that's the sanity check. Problem is you don't have to move very far at all to stay within sanity check bounds. If your box is less than 30y, then the moment you get hit by Landslide you'd not only die but you'd get flagged as a teleporter, because you sure moved very far suddenly! There are also player abilities that move that kind of distance (BLM teleport to ally, for example). Also, this routine would have to be updated each time there are new abilities that faciliate movement, and every enemy that has an ability to move you has to be accounted for. Teleport is usually caught because you've to temper with game data to send the fake coordinates, but catching it in real time, let alone correcting it, is very difficult.
