Look where speaking out gets you. Can't say I am surprised. But I am disgusted with their scamming ways.
Are they planning to do an exit scam? You should probably spread the word around to all your friends/online groups about this and ask them to withdraw the funds as soon as possible. From the links Slow Death mentioned above, it looks like the typical exchange exit scam. If I was you, I'd spread the word around and make sure people withdraw their funds.
