There have been tracing applications around for years now in this space. They've identified wallets & send micro transactions around to many to distinguish who is who in terms of dark markets, services, bad actors etc. Given the many hacks with wallets and also services selling that data believe me they know more than you are giving them credit.

In terms of the bad actions.. Those who are trying to hide money have known this for years so they are in different currencies that provide better privacy.

I didn't make any claims about how much they know.
