I started this diabetes-oriented website 2 months ago and started picking up some decent backlinks. However, I got more than 7000 backlinks from one site - diabetesdaily.com - literally overnight, and they are all pointing to 1 page on the diabetes website. I had done a guest post which was posted 3 days prior to this and I counted on getting 1 backlink.
I can't imagine Google finds 7000s links in such a short time 'natural'. Should I go ahead and disavow all of them?
I have all in all at most 400 backlinks from other sites, I'm attaching webmaster backlink data for the site.
