long_desc <<~LONG_DESC
Erase the server from the federation by broadcasting account delete
activities to all known other servers. This allows a "clean exit" from
running a Mastodon server, as it leaves next to no cache behind on
other servers.
This command is always interactive and requires confirmation twice.
No local data is actually deleted, because emptying the
database or removing files is much faster through other, external
means, such as e.g. deleting the entire VPS. However, because other
servers will delete data about local users, but no local data will be
updated (such as e.g. followers), there will be a state mismatch
that will lead to glitches and issues if you then continue to run and use
the server.
So either you know exactly what you are doing, or you are starting
from a blank slate afterwards by manually clearing out all the local
data!
