Hi every lemmy. I've just stood up a couple new instances and I've been hanging out in the Admin chat over at https://matrix.to/#/#lemmy-support-general:discuss.online. Someone there asked if they could view subscriptions so I wrote and shared the sql query. (could I have done better on the joins with 2 joins to instance?)

And that's when I realized what an invasion of privacy that is. Maybe there's an easier way to do it but could we add optional support for user key pairs, so that if I associated a public key with my account, everything related to me in the db gets hashed with that key? Then I provide my private key at login?

I say optional because I know that's hard for a lot of folks. But maybe there's a way to make it easier with something like letsencrypt at sign up so it would be trivial for everyone to do it.. Or maybe there's a way to do it globally with a central key common to all instances, perhaps paired with instance specific keys?

I understand there's other aspects of user activity that would be best made private to so this could also work, say for votes or whatever else.
