Requested feature overview description.
I would like a checkbox under the blacklist that says "Block locked tags", or possibly a special character to add to a tag in the blacklist.
Having this feature enabled would check a post for locked tags, and blacklist the tag even if it's locked.
Why would it be useful?
There's been a few cases where an underage character has had "cub" or some other highly argued tag locked out of the tags, but it still makes many users uncomfortable. Adding this option would be a "better safe than sorry" approach for users that absolutely don't want to see it, whether it be tagged directly or in the locked out tags section.
What part(s) of the site page(s) are affected?
User search, or any place where the blacklist is used to bring user relevant content.
