Good luck getting him prosecuted under any kind of computer abuse law. 
That would be like calling the cops on a sibling who is poking you, 
claiming that it's assault.

I doubt any ISPs will do anything about it. It's probably negligible 
relative to their total DNS volume, and would be more trouble than it's 
worth to add filters to block it.

The domain registrar is the place to go, I expect most of them have 
standard procedures for exactly this problem.
