I am guessing you mean nsec, as with npub only an app cannot modify your contact list

Yes oops!! I am talking about nsec
Ahhhh well that looks like what mightโve happened. Darn
Try using https://metadata.nostr.com/ to restore your follows
Tempting, but before I begin โฆ
Iโm still having trouble with people Iโve unfollowed still showing up in my feed. Sometimes to the point of it actually saying Iโm following them again, but weirdly, more frequently, their notes are just there and itโs acknowledged Iโm not following them.
Itโs not because of hashtags, and Iโve logged out and back in but this still happens, in both Damus and Primal (mostly Damus).
I donโt want to make the problem worse and refollow lots more people Iโve unfollowed ๐
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, youโd have to ask the creator and the community. Godspeed, and lmk what you learn ๐
nostr:npub1e2rd2k45ym2jmctnysfadxumrvrr57vqj69ck6trt2y62c40r0kqs9lx8t I can see the your latest follow list in the Fountain relay has many pubkeys - it doesn't seem to have been nuked. We also have logic in the app that prevents signing a brand new follow list so this shouldn't happen.
Can I ask where you saw your empty follow list?
Correct, itโs not completely empty, but I went from 500+ to 300ish. Iโm going around now refollowing people I know I didnโt unfollow.
I believe the loss of 200ish follows predates my use of the Fountain update. But Iโm less sure thatโs true of my apparent โrefollowingโ of people Iโd unfollowed.
Iโve been seeing notes from unfollowed people for the longest time of all these bugs, but it at least hadnโt been claiming anywhere that I was still following them.
Itโs entirely likely it wasnโt Fountainโs fault, I just donโt know what happened, and I think it is the only new client Iโve used.
The timeline here is so uncertain, sorry!
Ok interesting. I did some investigation and it looks like your latest follow list was only on certain relays. Other relays had various copies of old follow lists. Fountain does try to find the latest follow list but it's possible that it didn't. I have updated the logic for searching for the latest follow list for the next version which should catch cases like this. I'm still not sure it was Fountain that did this - but either way the additional checks will be helpful.
