They titled this thread The b-ex.io exchange is being scammed.

Thats hilarious. How much money has troyleroy76 scammed from you b-ex.io? Exactly $0. Meanwhile, here you are refusing to give him back his UFR tokens.
If they continue to refuse to withdraw or ask you for more apologies before returning your funds (which is totally illegal), file a legal suit with the Securities and Futures Commission of Hong Kong and the China Securities Regulatory Commission (CSRC). Ask them to read these threads and determine the legality of b-ex.io's actions for themselves.
