anyone ever got limited or banned by a sportsbook, what happened?

Had a strange run the other month, not even a heater, just steady cashouts, low stakes stuff, mostly live dealer blackjack and some tennis plays. Out of nowhere my limits dropped so hard I could only bet like a few bucks at a time, and then a couple days later I couldn’t get any bet through at all. Never had any issues before, no chargebacks, all my docs checked out ages ago.

Honestly was just using a spreadsheet to track EV and avoiding the boost traps, nothing fancy. Never even bothered with matched betting or arbing. Made me paranoid about mixing poker and sportsbook accounts too. Curious what triggered it - too many withdrawals, betting the wrong markets, or just their system flagging something random. Would appreciate if anyone else ran into this and figured out why. Feels like they just didn’t like me beating live dealer for chump change.
