Rockstar Support site;
"In regards to reports of hacking and cheating in Grand Theft Auto Online, we are working on a fix that will remove any GTA$ gained through these blatant exploits, as well as prevent this from happening in the future. We'll also be taking appropriate measures very soon to punish anyone that we've discovered manipulating GTA Online in this manner (as we've stated previously, players who have received large sums of GTA$ but not engaged in any game manipulating through exploits can rest assured knowing they have nothing to fear).
If you have been gifted a large sum of money or collected a large bounty and would like to have the money removed from your account immediately, you can submit a request to us to have your balance properly adjusted. Otherwise, the money you've been gifted will be removed once our upcoming fix is in place."
... so much for the "its so widespread they will just give everyone glitching servers a pass" theory... be nice to have the game back
