IP, Email tracking over suspicious activity

CleanTalk Inc

The extension checks an IP or Email over the database of spam active addresses at cleantalk.org. The database contains up to 10 million records with activity for the past 30 days. It shows the history of spam attacks, amount of attacked websites, and a short description of the owner of an address. To perform an IP or Email address check, you need to highlight the IP or email address on the page and right-click and then click on the cleantalk.org lookup menu.
