Looking at the first link on Eternal Super Seiyan, at the bottom in the categories it says

Fan Fiction | Transformations | Page added by SuperSaiyanKrillin | Transformation created by SuperSaiyanKrillin | Power Ups | Super Saiyans | Super Saiyan Form | Fan Made Transformation | SSJ Forms | SSJ Forns

It appears that fan-fiction questions are on-topic on SciFi.SE, which suggests that they are workable on SciFi, but I am wondering if fan fiction/fanon questions should be on or off topic here on Anime.SE?, and if they are on-topic, how should they be quality controlled? (i.e. tags, guidelines, etc)

user18582: I would say that questions about fan-fictions are off-topic.
There are a few reasons why I say this:

People can say whatever they want in a fan-fiction, and sometimes
they aren't even related to the original anime or manga themselves.
Often, the answers to fan-fiction questions are, "We don't know!"
Fan-fiction questions can tend to be open-ended due to either bad storytelling or bad links to the original anime or manga, and it is stated in the help center that:


Chatty, open-ended questions diminish the usefulness of our site and push other questions off the front page.


Which leads me to: they distract from questions about actual anime and manga. And anime and manga are the whole spirit of this site!

To wrap up, I don't think the users on this site are entitled to answer questions about fictions of varying quality levels. That can get way off-topic, and it would create a whole slew of second-rate questions that people don't want to have getting in the way of legitimate, valuable posts.
