The only silver lining is that the author has no fucking clue about KYFMS, and he will probably be confronted by authorities.
He published under the name "The Mule" so they might have to do some digging, but I'm guessing this guy will slip up sooner or later. I guess it was being distributed online, so they probably just have to follow the IP addresses.
If he chose a pseudonym, he's too stupid to stop.
