Do you think it's normal for a sportsbook to investigate for more than 6 months?
Well, investigating for more than 6 months does seem like quite a long time. But I have seen such cases before. It probably depends on the type of investigation and who is conducting it. It may be a third party security provider so it is out of the casino's control. It does sound a bit on the longer side, though. A month or two should be the maximum in my opinion.
When I came across this discussion on another thread, my question was, what exactly is the supposed or suspected crime that the casino or third party needs to investigate before processing the withdrawal of the this user?
OP did not state or say any thing about being accused of commiting a crime or going against the casinos terms of service, what exactly are they investing that will take up to six months, it's my first time of reading about such to be honest.
