What does the Silver Flag (circled) on Full Tilt Mean?

[PLO8FaceKilla]

sometimes when i play different people on full tilt poker (where the pros play) I run into players that have what looks like a Grey, Circled Flag to the bottom right of the players avatar. its on the top right side of the name box.

what the hell does that mean?
some people have it, and some don't


I'm guessing Brad Booth has it but i haven't played him yet.
