I have no idea why those links are being made, but you can take steps to try to stop them affecting your site:

First, register the website with Google Webmaster Tools (GWT) - http://www.google.com/webmasters/tools/‎

Then use Google's disavow links tool to tell Google you don't want them to take any notice of the spammy links to your site.

The tool - https://www.google.com/webmasters/tools/disavow-links-main

A help page about disavowing links - https://support.google.com/webmasters/answer/2648487?hl=en

Note that you can add comments in to the disavow file, mention in there that you have no idea who set the links up or why.
