In fact they shut down Neteller a few years ago, the main way people used to get money in and out of poker sites. People's money was frozen in there for like close to a year I think. High stakes players, some of them had mid to high 6 figures frozen while one of the alphabet groups from the usa did an extensive investigation. Then some dick congressman/representative named Bill Frist snuck through an attachement to the port security bill (a post 9/11 bill basically most all dems and repubs were for making it illegal for banks to exchange money with online gaming sites.
The US gov't even went so far as to stop and arrest owners of some of these sites that were registered in countries like costa rica where they were completely legal as they were on planes that temporarily stopped in the USA from France to Argentina for example.
Back in the early days people could 'lend' mid 5 figures to one another over neteller with a phone call. When they shut it down people were not even sure if they were going to get their money back, bbut for anyone with over 10K it would be illegal not to. People got their money back but most of the casual (i.e. suckers) players stopped playing as it was more difficult to get $ in and out of the poker sites once this all went down.
Hell I stopped playing because too many american fish stopped plaiying, the suckers moved onto other forms of gambling because it became a hassle to get $ in and out of the sites.
I wouldn't worry at all about swapping off a few K here and there but if you want to get 2-300K laundered this way I would think they would look at your play to see if one player is dumping to the other. If your doing a few K here and there I wouldn't worry about it, if your talking bigger business I would strongly advise against it.
