roulette bonus terms say no opposite side betting but i only played red and some dozens

So I grabbed one of those shiny deposit bonuses and skimmed the fine print like I’m scanning a barcode. It says no opposite side bets - like red and black at the same time - which I didn’t do. I just stuck with red, sometimes dozens, sometimes a little street action when I got bored. Nothing wild, never hedged both sides. Now I’m worried about them flagging my play as a “pattern” or whatever and saying it’s voided because I was “playing it safe.”

Anyone else been hit with that? I’ve heard stories where casinos stretch the definition of “opposite side betting” just because you stick to the same color or keep changing your bets up, but isn’t that just normal roulette? I get it if you’re covering almost the whole wheel but I didn’t. Trying to keep things legit here and still enjoy a bonus without getting flagged like I’m running a roulette lab.
