What do you call??

If he runs it again, and there's contact with more than one screener, consider a multiple foul. That should put a stop to it, especially if you're shooting free throws before you get to the bonus, and he's suddenly 2 fouls closer to that bonus.
I like the idea of a violation, I just don't see that spelled out. It says in 4-24-9 that they can't do it, but it doesn't lay out a penalty like it does for swinging the elbows.
