Spam Activity: Top-level Domains Quarter over Quarter Comparison: March 1,2026 - May 31,2026

For purposes of observing change over time, it is useful to compare measurements and metrics over successive reporting periods. Such comparisons illustrate whether spam activities are increasing or decreasing, and where such changes are occurring. Such comparisons can identify TLDs that are persistently abused or exploited by phishers. Investigators or policy makers may focus on these for deeper analyses.

In the table below, we use the measurement reported spam domains to compare the ranking of TLDs for the two consecutive periods.
