Open a new meta question under the tag tag-warnings with the proposed text and the tag to which it should be applied. This will allow for community input to improve the text, if necessary, before we kick it upstairs.

Story Identification answers depend a great deal on how many details of the story you can provide in your question. Details can include where you encountered the work, a time frame when you encountered the work, and what similar works you have ruled out. Even small details can matter! We have a complete guide to asking, which may help you find more details to add. Please read Tips for asking Story Identification questions
