Dec 2019. We discovered an error in our computation of the total number of URLs requested for delisting. As a result of our correction, the total number of URLs dropped by 65,063 and the total number of requests dropped by 4,056. This correction is also reflected in all relevant data exhibits across the report.

We no longer count spam requests in the Transparency Report figures and we have deleted previous instances of forwarded requests.
