The end of trolling in America????
I would love to see this bill enacted just for the lulz of the potential situation where a person gets trolled, then they troll back using the threat of the law and then both end up getting thrown in jail for trolling each other. But realistically, this is a crazy idea, as much as I dislike trolling behavior if you can't accept that people might make it their business to screw with you online as much as possible then don't go where they are online or convince someone with some clout to get rid of them, don't go running to Uncle Sam.
I would probably be guilty of this law on multiple counts for some of the things I've said on IRC and I consider myself one of the nicer members of the channels I frequent. Just imagine trying to enforce this law on a place like 4chan.
