NO FOLLOW: Should I remove or disavow nofollow backlinks?

The quick answer is NO. There’s no point removing or disavowings nofollow links unless they are hurting your reputation, for example, if a porn or gambling site links to you. If the backlink is bad, you should try to remove it and then disavow it, even if it’s dofollow or nofollow. If you have a good nofollow backlink, you should leave it as it is because it might send relevant traffic your way. Nofollow backlinks cannot hurt your site.
