We have a collection of websites built using various CMS systems, and Webtraffic Exchange in particular was originally built with Drupal. The site has been around since January 2007, and we've added nearly 200 articles over time. During the course of its lifespan, we've lost our focus due to lack of time and kept the website unmanaged. After nearly 17 years, we realized that the site has a Moz spam score of 29 which is not a very healthy number. The primary reason for having such a high spam score was due to leaving the blog comment system open to the public, and not cleaning up spammy links.
