bc.game says “irregular play” but i only did small blackjack bets then one big slot buy

Ran up a balance on a bunch of small blackjack bets, just slow and steady. Didn’t even try to push limits or hit promos, just basic strategy and chilling. Then tried one decent sized slot bonus buy, not even a huge win, and now suddenly they flagged my account for “irregular play.” No crazy betting pattern or obvious abuse.

I’m not new to these sites and always figured as long as you don’t go all-in constantly or mess around with bonus abuse, you’re fine. Is this just their way of stalling cashouts, or am I missing something subtle in the rules? Feels a bit sketchy but maybe I’m overreacting. Kind of ruins the vibe for just wanting to do a normal session after work.
