Guys removing the info from Njump.me won't remove his identity completely from Nostr, Nostr runs on relays and media servers that cache information all the time, removing it from one place won't remove it. I still see my old profile picture and name appear from like a year ago sometimes when I first login to a service, it might suck sometimes but it's how it is and for a reason. I would recommend anyone posting sensitive content to do it from an anonymous Npub from the start which has never been associated with a name. Hope this helps.
