Couldn't said better. Btw, I can still bet on other betby sportsbooks with no VPN or proxies with max limit, and I even could withdraw today with no problems. After seeing the other scam accusations from users that got the same message as me, I'm 100% sure the restriction has nothing to do with Betby.
You won't face the same problem on other sportsbook right away. But sooner or later, the bet limitation will be applied on your account in the other sportsbook if the decision was really from Betby odds provider. We can assume that the decision was from Betpanda itself if you don't get limited or restricted on other Betby provider sportsbook. I hope you will give us an update about your situation in the future.
