+    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!
