promo terms say “irregular play” but dont say what bets actually trigger it

I was reading through some bonus terms and saw “irregular play” mentioned as a reason they can void winnings, but there’s zero detail on what actually counts as irregular. Like, are max bets after meeting wagering always out, or is it just bonus round hunting on slots? Some places mention single-line betting or switching up bet sizes a lot, but this one just leaves it vague.

I try to keep everything above board with my bonus strategy but this kind of thing just adds stress. Anyone run into issues where they got flagged but had no clue what triggered it? I wish they’d actually spell out the no-gos in plain language instead of keeping it so mysterious.
