That’s gotta hurt… how do you back that shit up anyway?
And if you back it up and shit hits the fan, how do you restore it?
And how does losing that stuff even happen in the first place?
Discussion
How it happens precisely is still a mystery (to me) but learned the hard way early after losing my followings and events a couple of times.
Some clients have an option to backup the people you follow and your events (Iris, Nostrgram) and then there is https://nostryfied.online/ and https://metadata.nostr.com/ that allow you to backup your stuff too.
I think this can be triggered by a glitch in any app you're authenticated on since the app has write permissions for your profile, follows/unfollows etc. But I'm not a nostr dev. Maybe someone else can explain better.
