If it is just one person who is doing the link adding for you, why not make them an administrator? (if you trust them that much). If not, it seems like they could simply be an editor with a lot of privileges assigned to them.

Also, can you help me understand, how can anyone delete listings without admin rights?
An editor can delete links only if you assign delete privileges to them. But in order to control the privileges they need to be a user in your system (hence the login system).
If you have an "open" directory, you could in theory, make everyone an editor.
Links allows for submission without admin approval also, but as I understand it, they still have to register/login before they can submit.
