I seen a post a long time ago that even if a market was compromised or LE controlled that you could still actually order on it with proper OSPEC and still be safe. How much truth is there to this?
I think it goes without saying if your vendor is comprised (LE has there PGP keys) then you are pretty much SOL as you are sending your order directly to them. If you use tail, Tor, and always SELF encrypt your shit should you in theory stay safe? I'm guessing they could still track your Bitcoin but it would still have to be worth there time to do so (high volume orders).
as a small time buyer if you use correct opsec you are safe.
use monero and no one can trace you payments either
