One of the downsides of closed source apps is you can’t see what it’s doing or file a ticket to fix bugs. This just came up with me with nostr:npub1yzvxlwp7wawed5vgefwfmugvumtp8c8t0etk3g8sky4n0ndvyxesnxrf8q which has a bug where it overrides your contact list if you follow someone in the yakihonne app. Hopefully it’ll get fixed fast. 

In general we have a nostr problem with replacable list events and how easy it is for apps to override and whip out lists.
