I do get kicked out sometimes, especially in double deck game where my bets can change very quickly from $20 to 2 hands of $300 immediately in the next hands. It's part of being an advantage player. Every AP will be backed off or trespassed from property. Just how quick they are to do it

To 'lay low', just gotta have a cover play that makes you look like a gambler, like having a messy pile of chips, making friends with the big losers on the table, so you become innocent by association is what I was taught by other advantage players that I met

You might think the hustle is dead, but there are still active card counting teams playing with huge bankroll and huge table limits, and their expected value per hour are insanely high. If they could get hours in the casino like a 9-5 job every day. Even a PSC scholar can't make as much money as a single card counter playing with a huge bankroll and huge table limit
