Spam Activity in Top-level Domains (TLDs)
March 1,2023 - May 31,2023

We analyzed the spam domains to see how they were distributed across the top-level domains. For our analysis, we extract the Top-level Domain (e.g., com, xyz, uk) from the hostnames we found in spam reports. We then rank TLD operators based on the number of reported spam domains and a metric, spam score.

In the tables below, we rank TLDs that had the highest number of reported spam domains for the period. A complete list of TLDs where spam was reported for the quarter can be downloaded in CSV format from the Records page.
