In case of fiat, banks often freeze the balance when an account owner reports a complaint to the bank. The AML score doesn't apply to banks they mostly freeze the money when they receive a complaint from the sender's account. Someone who sends $500 from his account to someone else account and then reports a complaint to bank's customer support that the transaction wasn't a legit or someone stole the account and then sent the money. In such case banks freeze the balance in the receiver's account.
So you mean if a blacklisted entity sends me funds, it won't be a problem for me, but if an entity on the BTC blockchain sends me funds, that becomes my problem? Bro, AML is real in banks, and they have to implement it by law. They can't just ignore suspicious activity or freeze a bank account without any reason. They have to run AML 24/7.
Although complaining is also one of the things.
Only a few no KYC exchanges have such options where they accept high AML coins but they charge some extra fee for such service.
If they are accepting your problems and giving you relief, then an extra fee is not a problem. Let's say if someone sends me high AML funds, where I would convert them, who would receive it from me, I can send them to someone and make it their problem but I would not want this. I would not put anyone in any trouble unless someone is offering a service to take your problem away from you. Now, no one wants high AML coins in their wallets, so a service like this can really help you because in these hacking and god knows what is going on things, we sometimes receive high AML coins even if we have no links.
