Generally though, if you don't want your centralized exchange account to be blocked/locked, just don't. Just sell the coins through peer-to-peer (Binance P2P, etc) as P2P buyers/sellers generally don't care about your coins' history.
And then just never use Centralized Exchanges again. Or use them by depositing Monero instead of the chunks of Bitcoin you receive. From my own experience, I had much fewer problems using Monero than depositing Bitcoin UTXOs I received from Peer to Peer trades.
How likely is it to receive a UTXO with a history of Mixers from a Centralized Exchange withdrawal versus how likely is it to receive one from a Peer to Peer Exchange? I believe using Peer to Peer puts you at a much higher risk of having your Coins seized by the Exchange simply because a Peer to Peer user would probably use Mixers or Coin Join too, so to the Exchange your UTXO is now 'dirty'.
So once you go that route. Just do not use Centralized Exchanges any more if you do not want your UTXO to be flagged and inspected in detail by the Exchange.
