this kind of thing usually happens in casinos that are almost bankrupt. or indeed their reputation has started badly. so they no longer care about the data being sold. because maybe casinos like that can close their casinos and do similar businesses with different names.
Wether bankrupt, gaining or loosing members trust or not if they want to sell clients data , they could do it as that is just their ways. If I may ask do you know what goes on within the team members? I know you would tell me no. That is the more reason there is the possibility of they trading with their clients data which is possibly right. Most people have no Idea all these they do and at some point, they act very strange of blocking and suspending clients account which is very terrible and frame up stories just to get data from the client before releasing the wins to them and in some cases, they do not give them their wins not to talk of their investment..
