It is not at all error, this is a problem due to outside influence, maybe the hacker has broken into the database and tried to steal it to sell to the outside. All exchanges that require KYC to do so intend to sell all of our information.
Even with Binance, they do the same thing. When tens of thousands of KYC sets were leaked in 2018 by a hacker, they alleviated users' anger by allowing them to transact without KYC. But anyway, it all came out and exchanges have the same mechanism. So we should only trade with exchanges that don't require KYC provision, which makes it much safer for us.
