|
|
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!
