Wait a minute here...........We are forgetting something...........Eric, Is it actually a working link from your site to their site or is it just a text listing. If it is just a text listing.......then I would inquire as to why the removal as you are stating that you deliver to that institution......NOTHING MORE.
If it is a text link, clickable link, or other type of link, then I could see the removal request.
