I don't know if you've ever been to a real casino, where you are monitored 24/7 and you are not free to do anything, simply if you win too much you are out, either you cheat or not, you count cards or not, they catch you and throw you out, you can be the best card counter in the world but if you are inconvenient they cut you out
This is reality even on online casinos, not that because you broke one of their terms but because you win too much and you're account were flagged as suspicious so, it's the same, its annoying and you can't do about that.
