How to enable content filter on ao3

If you’ve “accidentally” disabled the content filter on ao3 (which admittedly simply warns you that you are about to read a rated fic [mature, explicit, not rated] and asks if you’d like to continue rather than completely preventing you from reading it), here’s how you re-enable it.

First, go to your ao3 account profile. Then go to preferences. And then uncheck that box in the display section that says “show me adult work without checking”.

Once its unchecked, ao3 will start asking if you want to see a fic that is rated. You can still opt-in to reading that fic but if for some reason you didn’t check the rating or tags this will give one more checkpoint where you can simply choose to not engage with something you won’t like.
