I suppose it's possible that the FUN-unlocking system isn't automated and the person who manually does it is busy, but that seems like kind of a silly thing not to automate.
I can't imagine unlocking FUN tokens is done manually.
There are lots of users at freebitco and FUN tokens should be unlocked automatically when the locking period ends.
I locked my tokens several times when the service was working well and I remember they were always unlocked without any delays which meant that it was automated.
