casino says my slot play looked suspicious because i changed stake every few spins

so i usually bounce my bets around on slots, sometimes low, sometimes ramp it up for a few spins, depends how the streak feels. lately got a message from the casino saying my play patterns are "suspicious" and they wanted to review my activity. seems wild cause i just thought mixing up bets was normal and keeps it interesting. i get that they’re watching for bots or weird stuff, but does switching up stakes really make me look like a scammer? feels like overkill, but your call.
