I have seen a case today that Winna blocked a user account for value betting, and they didn't even refund the initial deposit, which was $2000. I asked Bennett if he cares about telling us why they confiscated the funds while the standard behaviour is to return the initial deposit.
Winna representative has said the same thing on the two scam accusations post (
case 1,
case 2). I just checked the odds provider of Winna sportsbook and found that it is Betby. Other sportsbook with Betby provider usually does the same thing to value bettors.
The refund of the deposits is given when the users get caught on their first withdrawal attempt, or if the user's overall PnL statistic is negative. Otherwise, betting sites confiscate the final deposit as their anti-fraud system costs if the users in profit for their past withdrawals. I guess both of those users are overall in profit at Winna.com.
