I recently purchased a site. Looking at its backlink profile, links from directories have been added a few years back. A lot of these directories look old (copyright date is before 2016 on their sites), others look like clones of other directories, just with a different theme and name. Should I be disavowing these? These links may have worked years ago, but now they look really spammy. It is like they used a free tool to just auto submit to directories. I understand not all directory links are bad (like the ones you pay for and the ones that are curated by an actual person).
