and no most casinos don't restrict "any kind of arbitrage" only the scam sites do, even though this is not what I was doing.
No, you're completed wrong.
It's not about scam site. It's about the policy term & condition, some casino not welcoming or accepting arbitrage doesn't mean they're scam. It's the policy and rules they want to set up for the site and once you register.... you will accepted & comply with their rules.
It's mean, even from your self arbitrage is not illegal but since they restricted those scheme. You're not allowed to do that's.
Those rules, is basically a same way for casino player. Especially Blackjack in Landbase casino, card counting is not illegal but the casino still can refused you to play or you not allowed to play any blackjack games. Either you got back off with the reason private property & trespassingor or your bet size getting locked without adjustment to low and high.
Plus, based your explanation seem like you're advantage player. No wonder you got flagged by a casino, I believe not only in here on every casino you're gonna to play (especially for a casino using the same provider) your season play are mostly recorded by provider and they will alerted every casino are using their provider sportbook.
