Full Tilt can no longer tender a viable claim to your funds as they have legally forgeited their right, if any, to collect same predicated on the allegations as set forth in the underlying unseaded indictedment in the Southern District of New York. Their deal with the Uniteds States Attorney's Office limited to facilitating the RETURN of funds to the players, and specfically does not permit the site's attempt to COLLECT funds.
Only in the event that somehow their is a global settlement with the United States Attorney's Office whereupon the site(s) agree to act in compliance and not permit any gambling from US Players, could your money be subject to collection. At present, any and all of the payment processors are under Indictment for serious allegations that include, and are not limited to money laundering, fruad, inter alia. God Help them if they amend their complaints on file, and include allegations for RICCO Violations!
I would advise that you treat the money as yours and not subject to collection, and while there may be some collecor attempting to collect on behalf of Tilt some time in the future, I would not worry about same, and you can guide your conduct and not worry as when Party Poker
left the Market as the dominating number one online site, their forfeited tons of outstanding money to avoid prosecution.
