I think you need to take a look at the page and how these have been used because it sounds like you haven't understood what the actual problem is fully.
With regards to relevance, it will probably give search engines signals that this page is no longer relevant and therefore affecting the frequency of the crawl for that domain/subdomain/page
It won't do that because they aren't complete links.
This is basically a means to an end. It serves a purpose and while there are better options to achieve what they want, this is certainly not an SEO issue.
