What’s the purpose of the archive tags?
The purpose is to identify subjects that have been the subject of substantial, recurring debate in many sectors of fandom and provide an easy way to warn for those subjects (though a choice not to warn is always acceptable as well). […]
What do you mean by “underage” in the archive tags?
Underage refers to descriptions or depictions of sexual activity by characters under the age of eighteen (18). In general, we rely on authors to use their judgment about the line between reference and description or depiction. Sexual activity does not include dating activity such as kissing, but again, we rely on authors to use their judgment about what is generally understood to be sexual activity. An author may always specify the age of the characters.
Why is “underage” defined as “under 18”?
Though there is no international consensus, there is a trend to focus on 18 as an important age in regulating depictions of sexual activity (as opposed to actual sexual activity/age of consent, which is regulated in many more varied ways). […]
In short: You can post sexually explicit fanfiction about characters under the age of 18 to the Archive. We just ask you to mark it as such (or signal your choice not to warn). If you don’t, and another user reports your work to our Abuse team, they might contact you and ask you to add the warning (or signal your choice not warn).
If there’s anything in particular you find concerning about this, please contact Support who can forward your request to our Content Policy team. Thank you!
