XF 1.5 How to implement the link proxy in addons?

It only applies to external links using the URL BB code.

You can actually manually create the links in HTML, they look like this:
<a href="https://www.avforums.com" target="_blank" class="externalLink ProxyLink" data-proxy-href="proxy.php?link=https%3A%2F%2Fwww.avforums.com&amp;hash=24f573fe00977240c5098a2388329935" rel="nofollow">AVForums.com</a>
The key things here are the href of the link is obviously whatever the original link is, a class of "ProxyLink" and a data-proxy-href attribute containing the proxy URL -- this is potentially the complicated bit.
$hash = hash_hmac('md5', $url,
   XenForo_Application::getConfig()->globalSalt . XenForo_Application::getOptions()->imageLinkProxyKey
return 'proxy.php?' . $proxyType . '=' . urlencode($url) . '&hash=' . $hash;
That's how that's generated in PHP ($proxyType would be 'link' for proxied links).

I'm actually unsure how that would help.

Stuart's Editorial system is mostly an external system. It doesn't use the BB code formatter to output content. I suspect it is written in HTML in the editorial system, hence my comment about manually creating them in HTML.
