I contacted them again about your issue, and they replied to me. But the reply I got from them was actually pretty useless, so I didn't tell you again. They think of you as their competitor and consider it an attack! Isn't this really ridiculous logic? I don't know why you choose these types of exchanges, they are always waiting for crypto users to send funds to their exchange, and they will scam them!

This is the worst thing I've seen from an exchange. First, they asked for information because the amount is more than $10k. Then they made up a story about tainted coins and some non-existent regulatory requirement for KYC and SoF. This is probably the peak, it is a competition from which they froze $11k.
