Ah just got the answer from someone whose job is to track tainted coins. Seems like it's possible, but registering an account w Chainanalysis ranges between 70 to 100k per year~~
Not worth the trouble then.
You might be confusing the act of chain analysis with Chainalysis, the company.

Thanks for clarifying. I should have been clearer in my choice of words. Also, regarding the use of the word coins, it'd have been better for me to talk about UTXOs all the time instead.
