Moderators can choose closed sites as migration destinations
Now I don't know what happens if we go through with this migration, but it would probably lead to the post being lost in some vortex of doom. Could this be fixed?
Edit: OK, I tried it with a dummy post. The migration is immediately rejected (i.e, the close reason is "off topic", and our good friend Community♦ locks it). Not too bad, but it's still a bug.
