From their response in this thread they stated that they could/would unlock OP's account, did they not?
They should get on it then. I didn't get that impression though. And their posts in their Russian thread seem to indicate the opposite.
And if the OP did as LiveCoin claims, threat their staff (we don't have the full details) then there may be more to this than what is being displayed here.
Mostly irrelevant, at least to me. I supported the flag after Livecoin came over here and confirmed that they're holding customer's funds hostage because the customer posted some "information". I don't particularly trust the OP's story and I don't have to, but whatever the OP may have posted doesn't excuse Livecoin confiscating OP's funds.
