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.
JokerChange PMed me before deleting that topic and was talking about how to develop the service and the best suggestions so perhaps they will redesign the exchange, but in any case there is no relationship between them and ZeusMEX.
AB de Royse777 as their advisor on the forum, you should suggest to ZeusMEX, maybe it's the right time to lock this thread.
