Did I understand this correctly? Some obscure cryptocurrency exchange gives itself the right to confiscate the funds from their customers based of an analysis of some self-proclaimed blockchain (anti)analysts who, incidentally, have absolutely no legal weight whatsoever? It is unacceptable for the exchange to make such a decision and, more importantly, to retain control over customer's assets.

The only thing I think should be done in this case is to flag the Openchange.cash exchange as malicious and warn any traders away from it.
