Just don't give out sensitive information and it doesn't matter for shit. LE is wasting its time and resources by monitoring Dread; the real big-shot vendors keep away from here and the only people who are stupid enough to give out personal details are little fish customers with shit for brains
However, LE don't just monitor, they go undercover, build up reputation, seek to mod, cosy up to admins, markets and vendors. LE goal is to blend in so they appear to be just another Dread user. They are cunt dogs that make it hard to know who to trust and corrode the Dread community.
There's no way to tell besides how they talk and act, just got to learn that. And if you can't, well you're caught already. ( Only if you're doing anything worth being caught and wild with OPSEC )
