Welcome to the Q&A Forum

Hi Bertrand13, Unfortunately, from Page Authority alone, we cannot determine if a page has been penalized by G. The page could be new, thin content, doesn't have many links pointing to it, hosted on a new domain, ect. You're on the right track for auditing the PR services. When pages, such as the one you've identified, are found the next step is to do a manual review of the page. When visited, is the page: Very spammy Little to no content Bombarded with comment spam Includes a ton of external links Completely unrelated to your niche Stuffed with keywords If so, then I would say you want to disavow that link and ask why/how your PR firm acquired the link.
