Specifically,
Protest Warrior reports that they've been in cooperation with the FBI and the Secret Service over leftie "hacktivist" plans, led by one Jeremy Hammond, to commit massive credit card fraud to the tune of millions of dollars (funneled into left-wing organizations) using thousands of stolen credit card numbers, to spread sensitive personal information (usernames, passwords, credit cards numbers, etc) to hostile recipients (including Indymedia and anarchist Web sites) and otherwise compromise as much of Protest Warrior's operations as possible.
In turn Protest Warrior has provided "a tremendous amount of evidence" to the FBI and the Secret Service and to the relevant credit card companies, and stringently upgraded its Internet security; only in light of Hammond's "Free Jeremy" site (where he accuses the two agencies of intimidation and of seizing all electronics in his apartment) is this being reported now by Protest Warrior, which in turn promises to release much more information on this situation soon.
