A few questions from a newbie
1. What's the security level/situation on Friendica? I remember with Mastodon people were being clear that messages weren't end-to-end encrypted, that your instance admin could read them. Is the same true with Friendica, messages and private posts?
This is not a criticism; Fediverse sites run by people setting up their servers works differently to centralised stuff. Just wanting to understand.
2. I see lots of mentions of the Bluesky connector, but generally without details. I've found fed.brid.gy/ that appears to do the link - is stuff like that what's meant, or is there another more official/advanced/whatever conector?
3. Lastly, someone I don't know has commented on a public post of mine, as they are entirely entitled to do! But now they appear in my 'Everyone' feed, which feels a bit weird. Can I control my Everyone feed?
