You're correct - I didn't mention anything about it not being prosecuted. It wasn't forgotten about however, I just couldn't think of any feasible way for the US to prosecute. I'm pretty sure the Isle of Man would tell the U.S. gov't to take a flying leap at any demand for co-operation. Of course, then all of a sudden, the Isle of Man would be harboring WMDs.
I suppose it's within the realm of possibility that the U.S. could prosecute, but like you, I just can't see that happening. It would piss off far too many people and I think some of those people probably have some pull on the hill.
If it did happen though, yep, it would affect me. A *LOT* of these sites would shut down and right quick. Take away the U.S. players and there's maybe enough online action to maintain one or two sites at most. (Party? Stars? I think the others would be gobbled up or fail rather quickly)
