One of my website's link is placed over a comment. This website has a "recent comments" section in the footer which is hence appearing on all the websites pages. All tools including - Google Search Console, Majestic and MOZ are showing 45000+ links from that root domain. Questions: Are these links harmful to my rankings? Should I get all those links disavowed? Should I disavow the root domain or leave the link that lies on the home page? What if there are up to 10 links coming from a domain? is that harmful too? Apart from disavowing, is there any other option to get this fixed? If at all this counts as an issue... Thanks in advance!!
