Ahhhh well that looks like what mightβve happened. Darn
I am guessing you mean nsec, as with npub only an app cannot modify your contact list

Try using https://metadata.nostr.com/ to restore your follows
Tempting, but before I begin β¦
Iβm still having trouble with people Iβve unfollowed still showing up in my feed. Sometimes to the point of it actually saying Iβm following them again, but weirdly, more frequently, their notes are just there and itβs acknowledged Iβm not following them.
Itβs not because of hashtags, and Iβve logged out and back in but this still happens, in both Damus and Primal (mostly Damus).
I donβt want to make the problem worse and refollow lots more people Iβve unfollowed π
How can I learn a little more about how this app chooses what to restore?
Damus has a known issue https://github.com/damus-io/damus/issues/1483
Regarding the restore tool, youβd have to ask the creator and the community. Godspeed, and lmk what you learn π
