From that monyet thread I'm seeing good discussion about the importance of encryption. To be honest a lot goes over my head but I wonder if a simple explanation could be of use to some of the relay operators whether they are the bigger paid ones or the self hosted relays that some people are running. So a question I would ask is should and how can a relay operator encrypt data on their server.

The depth of traceability extends to levels that you can't imagine.

Network modelling, habits, content posted, pictures, timing, etc.

And all this comes without including that people running a relay might not be that bright. And even then, if I were a malicious actor, I would take down silently a few relays and replace them with mine.
