Ultimately if you have used their platform - you agreed to the terms. By registering with a false or incorrect name or details you committed a fraudulent act or made a serious error when entering a contract.
Usually people don't need to "change their name details" unless they gave false details.
It is something you will need to sort out through their support ticket system. Ultimately though it comes down to a user error. (Deliberate or not)
Take in mind, all the users had Level 1 verification from the exchange. So exchange approved their right to trade earlier.
At my request to provide any facts of fraudulent activity, the staff confirmed that this is a general check.
Also how can TS-staff know in advance whether the data is right or wrong before the KYC-check? It's a vicious circle, we're coming to.
