The exchange did not take the money. Where is it written that they stole something from him? Show exactly where it is written that the exchange stole his money.
Here:
We are talking about blocking his account and while it is a temporary blocking, until all the consequences are eliminated.
It doesn't matter what you call it. The user cannot withdraw or otherwise take control of their money. If a person in a ski mask comes into a bank and says "put all your money into my duffel bag and I will temporarily block your access to it" - that's still a robbery.
Read this topic, read the posts of this user, look at his behavior. Nothing strange?
I don't care. I'm basing my opinion on LiveCoin response in this thread.
Well, if you do not care, then there is nothing to talk about. I also do not care, the user has a violation means should be responsible for their actions. Moreover, the Exchange made it clear that it needs to be done to simplify the process.
