WMT reports that 8-10 sites with "link building", "seo marketing", "backlink exchange", etc. in the domain name link to me from 300 to 1000 pages each, all with the same format, however, when I check many of these pages, my link is not there. Is this a WMT bug or the links were there once but already removed?
If so, am I a victim of negative SEO as I NEVER did any link building?
