Anything you submit is public. If you delete a comment, you’re only deleting it on your local instance, and it’s still saved in the database / visible to admins. Private messages are visible to admins.
Treat it like a public phpbb forum from 2001, not like a secure, encrypted means of communication. If you wouldn’t want other people seeing what you post, don’t post it, plain and simple.
(It’s just as “safe” as any other social media, which is to say, it’s not. Use discretion, be intelligent, and think before you post - this goes for the internet as a whole, not just Lemmy.)
Just to add on to this as the mod of a young community.
Mods can still see posts (and also comments I think) when you delete them on the communities they mod. Same with removed posts. So it’s not just admins that can still see things once they’re gone from most peoples view.
