I won't judge anyone by the general occurrence or at least what people perceive to be so. Nevertheless, do you view any reason on sight? Regulation?
If you are talking about JokerChange, then it will be hard for anyone to really know what happened, they recently came into the forum and i remember i participated in the discussion in their ANN thread.
Their rep was replying to queries from members and it looked like they were ready to make improvements in order to be more attractive to customers. So i am surprised they left this way, and their site also stopped working, it surely raises questions.
