i didn't say "no" i said "almost nobody"
just like tor's 3 hops 3 rounds of coinjoining pretty much wipes out any chance of making a positive correlation
blacklisted bitcoin can still be cleaned by applying it to fees because that ends up coinjoined in the mother of coinjoins, called "block fees"
i'm pretty sure that at least part of what the ordinals are doing is washing coins that are close to ones that have been marked
if you are dealing in big enough amounts of bitcoin to attract this kind of attention it is trivial for you to cover the cost of these processes so there's no excuse for getting caught
