Is This Banksy?

Is this Banksy? This photo was produced by the seller in question who was offering the truth behind who the artist Banksy is. The auction ended with the highest bidder sitting around $1,000,000. When contacted the seller was quoted as saying "I spent 3 years finding the answer. I was paid off, now I can tell you nothing. All I can give you is this photograph." This photo shows a person waving a hand at the camera in a 'Don't take my photo' face. Hmmmm! Was it Banksy that paid off this bloke?
