room says my fast fold volume triggered account review but im just grinding micros

Just got hit with some kind of account review because of my fast fold poker volume. I’m only playing micro stakes, so I don’t see how I could possibly be flagged for anything shady. I multi-table, sure, but it’s just regular grind speed for anyone taking it seriously, not some bot-level thing. No HUD, no scripts, nothing fancy.

Has anyone else been flagged just for doing long fast fold sessions at small stakes? Is there something about playing for a long stretch that sets off alarms on some of these sites?
