Google clearly tells me the earliest mention of Beckster is in fact in a Jan07 post by Gambler on PUATraining endorsing him, which I won't link to because I'm not doing their backlinking for them. He then gets a LOT of hits for things.
What was Beckster doing before Gambler first "endorsed" this guy after training with him? How did he meet him exactly given there was absolutely no mention and thus no knowledge of him in any of the communities preceding Gambler "endorsing" him?
To be fair. When I was last winging monkeybuster he was telling me about a few PUA's in London he had met. He told me Beckster was one of the best he'd seen.
