Add more tags to the protected categories

[Acenoid]

Hi there!

I am not sure if I'm not mistaken, but are there some tag domains like "Species" or "Carreer" that are not used in any available category?

I would recommend to add them by default to the protected categories. But their default (since they are not so common (?) , could be disabled.

This way I could keep the protection enabled, but change my "default" tags.

It would also be good to see where tags are being used and if they are used where exactly to easy up clean ups of wrong data.
