I know the forum is very rarely used for things like this, but there are folks who do not use the discord.
Please be reminded that in submitting an episode to the site does not entitle you to delete it days, weeks, months or even years after the fact. If you have a recent submission you want to delete for whatever reason, not a problem as you have the tools to do so until someone submits a child of that branch. Once that child is submitted you can no longer delete that episode, even if you submit a moderator request.
Fiction Branches is a growing story and contributed to by many authors over the now decades.
If you have submitted something a long time ago that you are embarrassed to be associated with now, please come on the discord either directly or via the IRC bridge on the site and discuss it with the mods, there are alternative options to simply requesting the content be deleted or blanking out an episode which the moderator and site team will not do for you.
If you are concerned that the content you've posted may be illegal, dangerous, illegitimate or somehow inappropriate, make sure you note that if you submit an edit request so the moderators are aware of the reason you want to edit a page beyond simply wanting to remove content.
