They are 100% aware of Monero lol the entire darknet economy runs on it.

How do you know?

Go on any darknet market and you will find either completely monero exclusive markets, or hybrid bitcoin and Monero markets where most vendors accept only Monero. Also D/Opsec in Dread basically says to only use Monero on DNMs. From this we can easily conclude that Monero is a vast majority of darknet transactions.
