I sure hope not, while Vraciu and I don't agree on everything, I've never seen him do anything as underhanded as this.
If Vrace isn't Palace Cobra then Quiet isn't double00PKer.
(even though the day double00PKer disappeared Quiet appeared with the exact same achievements, fighting stye, plane choices, score ranking, lack of vox, TDR and attitude.) He's also some Navy fighter pilot or something too. (go figure)
