Recently i bought a bookmarking service which consisted of 1k links, and to my surprise the bookmarks created tons of duplicate links: same page but under different urls on each bookmaring website, the result was 30k links in two days shown in ahrefs! The two websites for which i have purchased these links lost rankings, one dropped few spots on page 1 and the other to page 5 from page 2. Now i am thinking of disavowing the links but i don't like google to manually review the sites for obvious reasons! What's your experience? Does the tool results in a manual review?
