I set my PGP, communicate only with PGP (even if I just ask questions), but vendors reply me in plaintext most of the time.
I really don't want LE to have the oportunity to read a message saying something like: "Your heroin is on its way, thanks for buying from us"
Don't give me the "as long as your address is encrypted" BS because: 1. My user could be deanonymised, but if all my messages were encrypted they wouldn't know what I had bought. 2. I could have bought from 300 vendors and only one of them had been compromised. If everyone encrypts, they can prove one purchase, at most. If all of them confirm and give information in plain text I would be in serious trouble.
Yes, I've tried to ask others to use PGP with me, but they ignore it most of the time.
So if PGP is so extremely hard to learn to make it mandatory (this is also BS, if markets had it people would learn it in a few days), then at least give me an option to refuse non-PGP communication.
I would really like to have the ability to nuke all past information from a completed order.
