The commentators talk is major hindsight bias and people clutching at straws.
The whole Postle God memes
I think its likely that JFK was the man who implemented that. Now whether that is because JFK is a complete moron and believed that Postle was the greatest crushers of all time, or they were created in order to build a narrative that Postle was indeed a god to help hide the cheating.
Commentators talking to Mike on stream
All of these commentators must live in the area. Mike clearly spends a lot of time in poker rooms, so its possible they have known him for years even before the Stones stream. He has the person of a nice guy (conmen always are). Of course they are friendly with him. And also a commentators job is to get info about the hands, so yeah you are gonna see them go from the booth to the table to talk to the players.
Not wanting to rock the boat
How many jobs in poker like this are there? None of the commentators are great poker minds. All of their styles and thought processes fit this stream perfectly! - a friendly, local live low stakes donk fest.
We don't know their financial situation. Maybe this job was the difference between making rent or not per month. So yeah they made have been suspicious or heard rumours, but it's hard to pull that trigger.
Also the commentators switch up so often it would have taken some time to really start suspecting. Remember we are watching these hands in short clips, back to back, time and time again and knowing exactly what to look for. They are working, dealing with chat etc for 4 hours and then might not have another gig for a month.
It's very easy to explain 1 of Mike's sessions as just some punter crushing. We've all been at a table with a guy like that.
Being directly in one it
I just don't see this. You are risking the operation being leaked AND having to give someone else a cut. This is a 3 man operation at most IMO.
I still think Mike bought their friendship with the odd tip here and there and also getting dinners etc.
The only commentator who might be in on it is this guy. He is the only one who I get the wrong kind of vibe from and he has on numerous occasions talked down to Kasey and Veronica.
