This rule is simple. If a request is problematic, we shall not be bothered to serve a generic 404 or Access Denied page. Instead, we shall pivot it into a satirical or absurd parody, because, honestly, that's just more fun for everyone.
For example, if you ask for /epiclootstats/rules/3a/6/1, we shall give you a page that's a parody of a parody. But don't worry, it's all in good taste.
