Not that I am aware of. And I’m not so sure I’d want to know if there are.
DOJ has been pretty aggressive toward poker and financial sites - I figure it’s only a matter of time until they go after individual players, if there are any left able to play.
Perhaps the article is badly worded, but the above does suggest that three sites (Full Tilt, Absolute Poker, and Poker Stars) are implicated in this, with Full Tilt being the one currently charged with the Ponzi accusations. Further research shows that the three sites have been shut down (for Americans) since April, but as of now, only the FT site is charged with the scheme.
So you may correct my post, but time will tell if the correction stands. As of now, PS does seem to be paying back its American gamblers, while the Full Tilt site couldn’t, which warranted the investigation.
