if you call out someone as a scammer you should explain the reason. I am not familiar with his content/behaviour since i dont follow the poker drama but i doubt ultra successful people would have anything to do with Charlie if he was indeed a scammer
I think the argument is that he doesn't show his results and claims to have certain winrates without showing the results. Regardless people should do their own research and he's streamed and shown a ton of live play; including coaching sessions where people should be able to form their own opinions on the value of his coaching. I'd say it's far from an outright scam and that also has nothing to do with the video in this thread from the OP.
