I mean you all see my bets, all of them are on big leagues, all parleys (up to 10 legs). I've been with them for maybe about a year at that point, and I've pretty much gambled the same way throughout. If there's any merit to them flagging my account, I'm sure they'd be quite vocal about it and point out in which ways I've been an unfair player, but they have nothing.
I've had quite a nice streak and won quite a bit of money in the couple of months prior to the bets cancellation, in those situations the sportsbook are tempted to do something about your account. It's a fairly common business model, just confiscate the cash of your biggest winners and it becomes quite easy to run a profitable shop.
Yes, my thought exactly: if it's about a flag for --let's say-- arbing or syndicate betting or fixed match, they'll already be very vocal about it. But they didn't mention any of provider flagging you. Thus, safe to say, not arbing or other things that come from the provider. And it'll be safe to assume fixed match is not in the book either. Hence, the question, if you perhaps have any idea of what this is about?
Do you mind to perhaps tell me the strategy you use on placing those bets? How you pick the matches? Why you choose what and when and how. Anything you can tell us about your betting preference and strategy. Like... you bet last minutes [I heard this can be an issue too] perhaps?
