Issue when saving a guide containing specific links

Hi iFixit team,

I was translating this device page into french :

https://fr.ifixit.com/Device/Gateway_NV5...

But after I saved the translation on the iFixit website I observed that a link was changed unexpectedly.

The device page contain a link to a newegg page :

This link : https://www.newegg.com/black-gateway-nv5...

But after saving the page (or after generating a preview) the link is silently modified by the ifixit server :

By this link : http://www.anrdoezrs.net/links/8269773/t...

Their is two problem with this :

1) The site www.anrdoezrs.net is intercepting the original link.

2) www.anrdoezrs.net domain suffer a negative reputation and is blocked by lot’s of adblockers. Also, anrdoezrs.net is blocked by OpenDNS because the domain is flagged in the Advertising category.

So I analysed what changed the link and I determined that the change was made by the iFixit server while saving the modifications.

Here is a screen captures showing the http query in my web browser with the good link sent to the ifixit server (when I generate a preview of the device page):

URL and headers :

Content sent to the iFixit server (good link is indicated by the red arrows in the picture) :

Content received in the server response (html bad link is showned in orange in the picture) :

So here is my question : why is this link changed when I save a device page ?
