I won't disagree with you that there's the possibility of issues online or in club games . I will disagree when you say there is little to no chance in a casino. The only time I've ever seen cheating has been in a casino including one major casino in Las Vegas during a tournament series. Then just look at the controversies and issues at this year's World Series of poker. There were always gonna be people trying to cheat or take advantage of the system but I don't think it is as prevalent as you may think online.
That's the think there is honestly no way for us to know or the sites to know if players are colluding at high stakes cash tables. Bots don't worry/concern me much. After a very short time and with my 20 years experience it's fairly easy to spot or clear when there's a bot at the table. Simple to deal with. Not and tag it as a bot and report it. Till dealt with by the site avoid sitting/playing with it. Hell if I even get a weird or strange feeling about an account or notice something off when I'm doing a hand history review I'll mark players. Being mainly a Pokerstars player thou it's been a long time since I've come a crossed any probable bots on PS.
Plenty of stories about shady goings on in private clubs(online and live) over the years. Guys not getting not paid winnings, guys depositing and never seeing the money again. Hell any online site/club that allows US players can rip them and scam them endlessly with consequences. What/who is any US player is gonna call, email or contact about it. There is no when you play illegally and on unregulated sites.
Then you have sites who aren't even completely transparent/honest about their rake.
Personally it's only high stakes online I'd be worried about when it comes to colluding cause that's the easiest way to cheat and likely not get caught especially is guys have a bit of common sense and don't make it extremely obvious.
Guess your right about that. We just seen cheating at the final table of the
wsop ME this year. Nothing was done about it. Personally I'm always pay close attention at my local casino for anything funny and weird. Have never see anything.
Cheers!!!
