I think this happened to Mr.NVK before and this is his note about the incident
Just in case you need, here is my confirmation of the npub remaining the same.

## What happened? @#[0]
The original DERP; I accidentally took the Damus "Delete Account" as sign out (ie Delete Private Key). Which I do have a backup so was not very concerned and did the deed.
(IIRC that's where the sign-out button use to be)
Damus to comply with Apple Store has to have a "delete account" method.
So how does Damus do it? AFAIK, it authors an empty (zeroing) of the Kind0 (profile data), clients rendered it as "nobody" and adds a "deleted account" flag. This means that until this is cleared from all relays and cache you can't login into the Damus app. But this zeroing out of the meta data does seem to cause relays and other clients confused. The contact list (follow/followers) seems to also have been zeroed in some relays.
- The followers seem to be all gone, which is not a big deal ppl who want just go and refollow me.
- For the following list, I just need to go look at an old contact list event and manually refollow ppl.
Because this is not documented as a NIP it's hard to know which relays or clients are honouring the Flag.
I think once the Kind0 of the profile is fully propagated the Damus should let me login again. Maybe there is a bug or IP block on Damus too, can't login with other "non-deleted" keys even after re-installing the app (TestFlight version)
...and then Client/Relays confusion should end.
Going to take a walk... BRB
Basically, if this is what happened, you'll have to somehow repush your old kind0 profile to relays
