I don't particularly have a problem with the strategy, except that it sucks to watch. To police it maybe categorize it as its own kind of foul. If player A commits this particular foul he is charged with a personal foul and a conditional technical foul (this would not incur an extra free throw or possession, just count towards the penalized player's technical foul maximum of 2 in the game). This would limit the amount of times a player could commit such a foul and add a slight extra penalty for it. 99 out of 100 times it wouldn't effect the player fouling out by T's, but it would give the coach a little something extra to consider before employing the method.
