The [[Mediawiki:Sitenotice]] on the various Wikivoyage sites has a link "View this page on the old site" which appears to be inserted server-side in some non-standard manner. As search engines need to index "wikivoyage.org" (and not an archive, fork or mirror such as wikivoyage-old or wikitravel) any outbound links from Wikivoyage to old copies of the same data on other sites need rel="nofollow". Omitting this can incur some problematic duplicate content penalties from search engines, as they have no way to know that wikivoyage-old is *not* the main site.
*** This bug has been marked as a duplicate of bug 41983 ***
Not an exact duplicate as bug 41983 mentions only links to WT, not the "View this page on the old site" link to WV-old. They're related issues, but not identical.
Wikitext external links in pages get rel="nofollow" already. The 'View this page on the old site' link is inserted by JS here: https://en.wikivoyage.org/wiki/MediaWiki:Common.js (At least, on enwikivoyage. Other languages are probably doing it in exactly the same way.) Therefore, RESOLVED INVALID as this is not something to be dealt with on Bugzilla, a wiki admin needs to do it.
