Hi all, bug 42594 https://bugzilla.wikimedia.org/show_bug.cgi?id=42594proposes changing the default value of $wgNoFollowLinks https://www.mediawiki.org/wiki/Manual:$wgNoFollowLinksfrom true to false. The status quo is that, by default, external URL links in wiki text will be given the rel="nofollow" attribute as a hint to search engines that they should not be followed for ranking purposes as they are user-supplied and thus subject to spamming. If the change is implemented, you will need to change your LocalSettings.php to switch $wgNoFollowLinks to true if you want to keep the status quo on your wiki.
Please email wikitech-l about this proposal - here is a wrong place to discuss this.
