Thanks Nightcrawler, that's good info. I'd just like to point out that nobody on this forum should be grabbing PGP keys from clearnet key servers unless they know how to properly configure their PGP client to work over Tor. Key servers almost certainly log requests, so LE could create a forum account and post links like this to enumerate forum users. Or they could look for links like these posted on the forum and subpoena the key server operates for the requests. They couldn't prove you did anything illegal, but my philosophy is to never get my IP address on any lists in the first place, so I'm never on their radar.
