live casino says my play was low risk bonus abuse but i was just doing small roulette bets

so i just got dinged by a live casino for “low risk bonus abuse” but all i did was my regular routine of spreading tiny bets across red/black and a few numbers on roulette, nothing wild. i’m not out here stacking one side or hedging every angle, just keeping it small since i only play with leftovers from poker. they’re saying my playstyle was “against promo spirit” but i thought the whole point was to keep things chill and not go degen for the bonus. i feel like if i wasn’t using crypto, they’d probably just comp me a pen and send me on my way instead of writing up this novel about “risk profiles.” anybody else ever get hit for this doing normal stuff?
