A quick reply to a paragraph in a previous message that the mailing list 
never delivered:


There are 3 ways to prevent HTTP referrers, either in links, or in 
headers, or  with a dereferer service:

1.  https://caniuse.com/#feat=rel-noreferrer

You can configure this in PmWiki with $UrlLinkFmt (in config.php):

   $UrlLinkFmt =
     "<a class='urllink' href='\$LinkUrl'
      title='\$LinkAlt' rel='nofollow noreferrer'>\$LinkText</a>";


This can be easily set in a .htaccess file or other server 

   Header set Referrer-Policy "no-referrer"

The 2 first ways work only in recent browsers, otherwise you can use a 
"Dereferer" service, for example:

3.  http://dereferer.org/?https://www.pmwiki.org

For example, this should work:
   $UrlLinkFmt =
     "<a class='urllink' href='http://dereferer.org/?\$LinkUrl'
      title='\$LinkAlt' rel='nofollow noreferrer'>\$LinkText</a>";
