This script/stylesheet is for PERSONAL use only!
You are free to install this script/stylesheet for yourself, but it is not allowed to be used wiki-wide (e.g., in MediaWiki:ImportJS, MediaWiki:Common.js, MediaWiki:Common.css, MediaWiki:Fandomdesktop.js, MediaWiki:Fandomdesktop.css, or MediaWiki:FandomMobile.css), as it would violate Fandom's Terms of Use.

BlackDiscussions is a Discussions stylesheet theme that blacks out quite literally everything in /f.
Usage
Because personal CSS is not loaded on Discussions pages, it must be imported inside of a theme extension, like Stylus (install for Chrome, Firefox, or Opera).
Once you have a suitable extension for installation, you can add the following code to import BlackDiscussions:
@import "https://dev.fandom.com/load.php?mode=articles&articles=u:dev:MediaWiki:BlackDiscussions.css&only=styles";
If your style extension allows you to apply to pages that match a given regex, you can use the following regex:
http.?:\/\/.*\.fandom\.com(\/.{2})?\/f(.*)
