We calculate the bad reputation score by dividing the total number of maliciously-detected domains by the total number of observed domains from the past four weeks, and multiplying this ratio by a logarithmic factor to give a higher weighting to entities with a greater number of malicious domains - learn more. The data included in these charts represent domains seen within Spamhaus' systems. It does NOT represent an entire TLDs domain corpus. Other domains may be parked or used for traffic outside our sensors' focus, these are not included. This data does not reflect the speed at which registries respond to take down requests.
