Script to Crawl the web for Drupal Site owners

I need a script to Crawl the web for Drupal Sites that require Security Updates or module updates. The script should enable to specify the following: A. Location like Country, State, City B. Version of Drupal (Drupal 6, 7, 8) C. Security Update or Module Update I want the crawl to do the following: 1. Identify site 2. Find the contact information 3. Send a boilerplate email to the site owner 4. Insert the site information to a downloadable spreadsheet To test that it works I need to be able to test the script with three Drupal sites that I know of. I am also open to suggestions. So be creative. This is for Drupal Sites
