Wanderlust3, I agree that for the most part, he was a personable guy, but you must have missed the video when he announced that he turned off comments. He was hostile and rude to everyone.
Overall, I agree with your assessment. I don't think he's a scammer, just a dude with issues who couldn't take the abuse anymore. I can see where he may have been constantly deleting things. It may have been better had he just ignored all of the comments, as many on Youtube do. I know that's easier said than done.
