When you use a root article path, for [[/example.com]] getLocalURL will combine the "/$1" and "/example.com" together and return `//example.com`. This triggers a browser's protocol-relative handling instead of acting as a relative url. As long as you create an article at [[/example.com]] so that a live link shows up instead of an edit link links like `[[/example.com|Example]]` will end up as `<a href="//example.com">Example</a>`. Naturally this means you can abuse this to link to other websites bypassing nofollow. Additionally doing this will also cause Special:Random to randomly send users to other websites instead of pages on the wiki when one of the `[[/...]]` articles is randomly picked.
