Just a question though, does anyone really think the US government cares enough to do this? I know they COULD do it, but lets be realistic. As many have stated here, there have to be at least 20 out of the 535 in Congress putting in a little action offshore, at least with poker sites. A handful of Congressmen claim offshores are a scourge on society, but not too many seem to rush to join them in that considering this is a no-brainer. After all it would appear no one really votes on a pro-offshore ticket.
Just stating this because I don't think things will ever get nearly as bad as some concoct them to be. The only thing we have dealt with was first Jay Cohen, to show the US could get a conviction thanks to a misguided jury and horrendous judge. Then they used that to shake down some major media companies and threaten others with complete non-sense. To go from a mob-style shakedown to extensive bans on using a money transfer mediums is a huge step. Further they would have to be vigilant about it, because just as a banned site can show up in 15 minutes in another location, money movements are pretty much the same. You would have to have a big staff that went out and did lots of undercover work and research to make a ban even last a week.
Once again not saying they couldn't do it, but realistically would they go to these lengths?
