Players in the post can move around, but when they grab, push, pull and hold to either get to a position or keep their position then it should be called. Again sometimes an advantage is hard to tell when both players are doing the same things or when the ball is not going to that area. This is why you talk to them early and let them know that you are there. Then if they do not listen call the foul. All it takes is a couple fouls and this will usually stop being a problem.
