Scammers disguise themselves as a stock exchange. When you deposit your money, they block your account, ostensibly to check documents, while any documents sent are answered with "photo changed".
In the support service, there are most likely robots who always answer either "you still need to wait" or "you sent the modified photos." I believe that such an "exchange" should be blocked on all resources, such as Coinmarketcap.
How many exchange site you will block? And if you block all the exchange site who asks to verify your identity, then how you will trade? Regarding this robotic answer, many exchange site even on facebook frequently questions answered by the robot but robot cant answer all the question. Robot can only answer those question which has been set by the site admin.
