I don't understand why is livecoin making a big fuss. Unlock his account, Give his money back, problem solved and everybody is happy. What's so hard about it? Did he steal anything from the exchange? Is his money originating from hackers/terrorists? If that's a "no" then unlock his account.

Also you can't just silence people by weaponizing your ToS, that's not what ToS is for.

I get it, it is there to protect the exchange but what about the customer?

The Customer guarantees not to disclose any information, obtained from the Service support operator, in any channels of communication. Violation of this rule will lead to the account termination without refunding of the remaining balance of the account.
