Yeah maybe. Probably won't cus I'm busy and already spend too much time on this stuff as it is but maybe if I have a week off or something I'll take a look at it. Would also be cool just to test my skills and learn more about how this stuff works.
Also the fedi is even worse from that perspective, every admin by definition has the ability to impersonate/hijack the accounts of any of their users, and unlike nostr the admin can actually lock you out of your account.
My concern with nostr is more the fact that switching clients seems to be pretty commonplace and normal, when each individual client has the ability to steal your account. Seems like a way for a bad actor to fuck over a lot of people if he is smart/sneaky enough. On the fedi if someone made an instance with the intention of stealing peoples accounts, he would only be able to steal the alts that were made on his instance, not accounts that exist on other instances.
