The problem remains that centralized services, like the most popular CEXs get their 'risk ratings' for bitcoin transactions from service providers that don't see much differences between someone wanting privacy and someone trying to hide their illegal activities. So they group those two together. Even if you perform your own AML filtering in an attempt to block out the bad guys, your coinjoins will still be treated as risky by blockchain analysis regardless of who took part in them.

As I already said in a different topic, the fight isn't against illegal activities only, it's also against privacy. It's unwanted by those who are in power and who make the rules. You will never satisfy them and make them happy because they don't want you or the idea of you to exist.
