Hello! I see there’s been some confusion! Allow me to clear something up: AO3 is not a safe space.
Let me repeat that. Archive Of Our Own is not a safe space, not in the way you mean it.
Why does the Archive have a goal of maximum inclusiveness?
There are a number of wonderful specialized archives. Our aim with this Archive is to provide a place to preserve as many fanworks as possible. At the same time, the Archive software can be used by anyone to create their own archives, including archives limited to particular topics, fandoms, or ratings.
What kind of content do you allow?
We will not remove content from the Archive because it contains explicit material, as long as it doesn’t violate any other part of the content policy (e.g., the harassment policy).
One basic consequence is that users are responsible for reading and heeding the warnings provided by the creator. Risk-averse users should keep in mind that not all content will carry full warnings. If you want to know more, you may also wish to consult the bookmarks that people other than the creator have used to categorize the fanwork.
Some creators do not want to put specific ratings or warnings on their works. Our policy aims to enable creators to choose appropriate labels or to opt not to use ratings and warnings, with the understanding that some users will avoid unrated or unwarned content.
The ratings/warnings policy is really minimal. Why is this?
We believe that appropriate ratings and warnings are often in the eye of the beholder. Users who feel that a fanwork lacks an appropriate rating/warning are encouraged to try to resolve the issue with the creator. Users may also add tags of their own to on-site bookmarks of a fanwork, which other users can consult for more information. When those tags are present, you can click on the “Bookmarks” link at the top of the work to see them.
The stated desires/goals when AO3 was conceived and initially developed can be found here, on a livejournal post from @astolat (founder of VidCon, Yuletide, and AO3, and all around fannish legend). In short, the goal was “allowing ANYTHING – het, slash, RPF, chan, kink, highly adult.”
And that, in fact, is precisely what AO3 hosts. You see, AO3 is a safe space for fanfiction. It’s a safe space for people to explore all kinds of fannish content without fear of banning, deletion, or legal reprisal. It was founded, designed, and developed to be a safe space for fandom and fannish works.
There also seems to be some confusion about the nature of safe spaces vs. trigger warnings. A fannish work that merits a trigger warning isn’t something that doesn’t belong in a safe space. The trigger warning is what MAKES something a safe space despite the presence of fannish works that merit warnings.
Something else to consider: there are many other things that include het, slash, RPF, chan, kink, and highly adult material, in addition to incest, pedophilia, infanticide, necrophilia, rape, bestiality, sadism and violence, adultery, and all manner of other things.
So holding individual women (because that’s what fandom primarily is, women exploring their sexuality in a safe forum filled with other women doing the same) accountable for their fictional exploration of things that a) exist in real life in genuinely damaging forms, b) have significant impact on women themselves, thus leading in some part to the urge to explore those things safely, and c) have existing in movies, television, popular culture, the Bible, and in all of literature since literature began? Well, that’s just an extension of the same culture that polices women’s sexuality in the first place and drives them to find safe ways to explore it.
