Welcome to the Q&A Forum

I would personally remove the page(s), but you could also do the following if you are afraid of losing links from partners linking to your site when they see their links are no longer there. a) nofollow or javascript all of the links b) noindex, nofollow, noarchive the links page(s) c) block the links section in robots.txt at a quick glance or to a non SEO person it would appear that nothing has changed, in reality you neutered all of the links - you should definitely do something to protect your site.
