Spam Activity: Domain Registrars 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 suspicious concentrations of spam domains reported in registrar domain portfolios, and can identify registrars where phishers flock to purchase and manage spam domains. 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 rankings of registrars during the December 1, 2025 - February 28, 2026 period to the ranking for the March 1,2026 - May 31,2026 period.
