blackjack bonus says no “minimum risk strategy” but support wont say what that means

Working through the bonus terms and it says no “minimum risk strategy” or else they void the winnings, but the terms don’t spell out what exactly counts as that. I reached out to support and they literally just kept repeating the same thing, wouldn’t give examples or any clarity. Not sure if betting even money hands, like backing up with insurance or flat betting, is going to trigger their system, or if they’re just talking about more complex stuff like counting or bet spreading. I do keep my bets predictable for reliability but obviously don’t want to get flagged.

It’s frustrating since it feels like if I make a profit, they could just claim “minimum risk strategy” and deny the withdrawal. Curious if anyone’s had trouble getting paid for similar reasons or if anyone’s seen what kind of bets get flagged.
