Im not a fan of no identifiers. Sure simplex is secure with it but I would like to see something like simplex that uses 24 word seed phrases to generste millions of unique identifiers the user can easily backup and restore from a piece of paper and not from a digital backup file.
Why not a community
!lemmyinstancegraveyard@lemmy.world
And a community for peertube and plume instances
!peertubeinstancegraveyard@lemmy.world
!plumeinstancegraveyard@lemmy.world
Someone on kbin could make a kbin graveyard community.
