Press and analysis 2
AnalysisD2-C672
The SpamBrain launch year mentioned on stage, with hesitation, was 2022, which does not match Google's documented 2018; 2022 is the year of the improvements described in Google's 2022 webspam report, so cite 2018 as the launch year.

AnalysisD2-C675
The '5 times more spam sites' figure said on stage matches Google's 2022 webspam report, but the report compares 2022 with 2021 (and gives 200 times since launch), not SpamBrain with earlier algorithms; quote the documented comparison.
