They should pay both winnings and deposits. No book in the world has a rule against "Value" Betting. It would mean that no one could ever win sports betting at XYes. All other books pay out in full and then limit the person.
I’m not an experienced sports bettor myself and, as far as I know, no casino has a clear rule in their ToS that prohibits value betting. However, I also know that most of the bookmakers don’t like it as they consider it an exploitation of their system to the player’s advantage, even if it was done intentionally. Therefore, aside from limiting the user’s account, many of them will also void the bets involved to cut losses.
Just to be clear, personally, I don’t consider value betting cheating since it’s the bookmaker’s responsibility to make sure their odds are accurate.
They said that i did valuebetting because they took some of my bets and compared them with other bookmakers. But i am sure that i could find many other bookmakers with odds over the ones that i took. In any case, whatever are the odds that i bet, i bet on what they were offering. From the other scam accusations, everyone was accused for the same. This is their actual excuse to steal their clients.
