Makes sense, since they don't use that tag for posts referencing the site. They use danbooru_(site) instead.
I don't really see the need for this. It can't be added on Danbooru mainly because they had issues with Google search, where searching Danbooru would for some reason lead to a tag search for Danbooru on Danbooru. Using "Danbooru" as the copyright tag would have thus led people from Google to pictures of Albert, or other such things they were likely not looking for. It still happens with danboru, though that tag is empty.
