Honestly, I can't see where it would be an issue. I'm no genius when it comes to OPSEC, but under the assumption that you're using encryption for your address, and the vendor is not LE, what does operating the server do to catch buyers?
Frankly, if the FBI is running Evolution, and transactions still go alright, I don't give two fucks.
But aside from that, why has 'Evolution = honeypot' been a continuing argument? I know some use it as satire of the frequency of posts mocking Evolution, but is there actually any cause for concern?
Well if Evo is run by the feds, I gotta say thanks mister federal man for getting me high as fuck for months now.
