Very interesting. @nopara73 had an account in Coinbase which he hadn't used in more than ten years. Then, suddenly he received an email saying that he had been deplatformed because his account had engaged in prohibited uses.

As you should all already know, exchanges spy on you not only before depositing but also, and even more importantly, after you withdraw from them. That means that if you did something that they don't like, like coinjoining a UTXO that they know was yours, they will close your account.
