I would like to get some experts and experienced opinions on this. So we see number of backlinks to our website where some to many of them are really anonymous and we don't know whether they are helping or hurting us. But we come to know the estimated spam links by some spam score from Moz. Do we need to disavow such links which fall in orange and red category about how dangerous they are. Really do we need to disavow these links? Google claims that they gonna ignore such links and other way they ask us to disavow any such links we are sure about hurting us. Finally landed in confusing land. How we go about this?
