Remember hansa?
They said they intercepted all autoencrypted messages and orders, personally I think this was a scare tactic as Ive only heard of a few vendor busts and maybe 1 or 2 customer busts.
I knew someone who used auto-encrypt and nothing has happened to them at all.
Anyone think hansa was a big ol' lie?
Good vendor opsec would basically leave them dead in the water for the most part.
You could have the proof of purchase + a users address & that still won't get you convicted. No drugs, no charges, or at least any that would stick.
If it's true it proves how difficult it is to catch & prosecute us without real concrete evidence.
