You can type pretty much whatever you want as far as questions about product or pricing or whatever without PGP. If a buyer absolutely wants me to respond with PGP I will but for the most part its meaningless except for where the identity of the person behind the username is being used.That's the key - even if the site servers got siezed and everything was fine-toothed by LE, as long as your actual IRL information is PGP'd they have nothing. Just that some party in this country or that country wanted this, bought this, sold this, etc.I usually just respond with a sort of "fluffy" response if someone PGP's me a message - unless there are pertinent details then I ALWAYS PGP. Buyers you should NEVER put your shipping information outside of PGP. Other than that it's not a big deal as far as I'm concerned, although your level of anal-retentiveness can be as high as you wish. Even though SR says all shipping information is destroyed once it's confirmed shipped, you never know (and there are hundreds of items "awaiting shipping" on a given day that LE would have full customer info on.Play safe when in doubt. At a minimum encrypt your shipping information, no exceptions.
