The Dream Market Honeypot is only possible because SpeedStepper isn't required to sign any messages.
When Dream gets taken down, a la SR2, we're all going to say "We should have known! We could have prevented all these arrests"
I would recommend that every market maintain a canary, or at least be able to prove that they still control all admin keys on a regular basis.
In the meantime, if you are saying anything on Dream, without PGP, or if you're buying anything more than personal use amounts, you're taking a huge risk. If this is a choice you make, then you don't value your freedom or the freedom of your customers, and will have no room to complain when you are serving your time.
As they say in the legal realm: Assuming facts not in evidence.
Read-up on what those, and under what circumstances they're useful (e.g., gag orders), and you'll soon realize that they're not really applicable to illegal conduct engaged in by anonymous individuals.
Scenario 1: A bad actor hacks/infects a market server and acquires one or more private keys belonging to the admin and/or market. Now the bad actor can 'prove' (i.e., pretend to be) he is in possession of the key. Not really helpful in an anonymous world. Scenario 2: LE physically busts the admin and 'flips him,' or coerces him into handing-over passwords/private keys, and/or masquerades as the admin using the seized keys. Not really helpful in an anonymous world.
What does that have to do with Dream? If you aren't encrypting your address or sensitive messages on any market, you're taking a huge risk. In fact if you order anything illegal, even if you encrypt everything, you're still taking a risk. Choose vendors carefully, encrypt sensitive info, and let's keep the tin-foil hat stuff for Tuesday's thread.
