> FlyHosting, a dark web offering

And then:

> An ad for FlyHosting posted by the the user “bnt” on the now-defunct cybercrime forum BreachForums

So we have a dark web 'offering' advertising on a clearnet forum. This is a conflict of interests IMHO. You're either fully operating on the darkweb or you're not. Clearnet e-crime sites are famously de-anonymized. It just takes a payment from PayPal registered in your legal name to buy hosting services, and boom: you've been decloaked by the authorities.
