Anyone have some guess as to how the parentheses for https://booru.allthefallen.moe/posts?tags=jinora_%28the_legend_of_korra%29 began when AFAIK there isn't any other char named Jinora?
https://gelbooru.com/index.php?page=post&s=list&tags=jinora has 46 hits whereas https://gelbooru.com/index.php?page=post&s=list&tags=jinora_%28the_legend_of_korra%29+ has 28 so we see something of that dichotomy...
