Or you are a scammer who try to extort the casinos asking for money for your silence or i dont know.
I see your profile and you have the exact problem with other casino. Im not saying this its not true but... its suspicious. If you are really innocent i think you have some problem with the IP your use because maybe the IP its related with some groups of cheaters of something like that, as far i can see you are not betting with really high ammounts of money so its really strange to see a bookie limiting your account.
Another variant can be your bet patern its suspicious but i dont know and i also not support that shit from any bookie.
