Sometimes, IABot will overwrite an another archive site a ghostarchive link that has already been placed in a cite web template when someone uses the management interface. Of course, this isn't a big deal, if wayback has the archived page as well then that should be fine, but sometimes there are good reasons for using another archive site then Wayback (e.g: broken websites on Wayback, certain content doesn't work on it).
Of course {{cbignore}} exists but i don't think thats necessarily the right way to go (or maybe it is)
Is this intended behavior or a bug?
