Its the most infuriating experience to scroll through a tag with all your custom filters in place only to still encounter untagged x fem reader fics.
Y'all it is not that hard to add one word to your tag salad.
"x reader" does not mean "female reader" by default.
At least let people who don't want to read x fem reader have the choice to not read it. By not tagging it, you're taking away that choice.
