I got 800 social bookmarks from a fiverr gig (somehow) accidentally. Unfortunately more than %80 of these social bookmarks are from deindexed .info domains. The target URL for social bookmarks is homepage of my money site and has DR 49. So it is a very import website for me. The owner of the gig does not remove bookmarks and tell me to use disavow tool. Should I use the disavow tool in this situation?
