help me out with a search filter? I'm sure there's a way to do it, but I can't figure it out. for example:
I never want to read RPF. it's a big squick. There's music RPF and Actor RPF and SPORT RPF but people rarely TAG their fic as "RPF".
So if I'm searching an author's or collections 'works' or searching through an existing canonical tag's results (let's use #Dom/sub);
HOW do I exclude all the fics within the RPF genre?
I'm going to recommend using a site skin instead of using filters. This is because there's a limit to how many filters you can apply. Each filter adds on to the length of the URL that populates your results, and at a certain point that maxes out and you won't be able to load the page anymore.
Not to mention, there are a lot of fandoms, for example bandoms, that don't use RPF tags at all. The fandom itself is for real people, so the RPF/RPS tags are assumed and not necessary to add on. Using something like -RPF in your filters therefore, won't filter those out.
With a site skin, you'll be able to hide fics with any number of tags that you want, and the list will be infinitely expandable. You only need to create the skin once and then edit when there's a new tag you want to hide. You won't have to save a set of filters - in fact, you won't have to think about it at all. You'll just browse the Archive normally and none of the works with those tags will appear for you.
Instructions for how to block tags with a site skin can be found here. Bonus instructions for blocking a user, a work, or a series can be found here.
i recommend creating a site skin just for blocking those things. That way, you can pair it with any other site skin you might want to use.
To combine skins, create your blocking skin and then scroll down to the bottom of the CSS box and tap on the button that says Show.
This will open up a menu where you can Add a Parent Skin
Just start typing the name of the skin you want to combine your blocks with, and it will autopopulate for you from a dropdown, just like searches and filters do
Once you've got all of the tags (and works and series) blocked that you want to block, you can browse AO3 normally. The things you've blocked will be invisible for you on the site, so if an author has 10 works and 2 of them use tags that you've blocked, you'll only see 8 on their profile.
This might make the numbers on your filtered results look weird, but as long as that doesn't both you I think this might be your best bet.
