How to mess up your Hubzilla directory:
1) Decide to reset your hubzilla instance and wipe the db
2) Create a new channel with the same name (but different pubkey)
This is sufficient, but to make it even more annoying
3) change your mind and restore the old db
4) now the new channel is in the directory and utterly undeletable
I realize that the answer to this is "don't do that," but it's important to document failure modes.
