I woke up today to an email from webmaster tools saying that I have received a manual action penalty for unnatural link building. The problem is I've never built links to this site! It's around 5 months old and it's 100% white hat, no links, handwritten content. This leads me to believe that I've received negative seo, I checked ahrefs.com and it says no new links have been built to my site, I tried [link:www,site,com] and I still can see any links built. Does anyone know how I can check the links built to my site? My plan is to find the links built, disavow all of them and continue with the site but I cannot find any of the links built.
