We can instead look at the statistics for scanning of communications that aren't yet end-to-end encrypted, which will provide a good indication for the effect of bypassing encryption. [Edit:] I know this is not a great source, but from https://www.gov.uk/government/news/home-secretary-urges-meta-to-protect-children-from-sexual-abuse https://www.gov.uk/government/news/home-secretary-urges-meta... > Currently, 800 predators a month are arrested by UK law enforcement agencies and up to 1,200 children are safeguarded from child sexual abuse following information provided by social media companies. There are also some interesting NCMEC statistics which provide a sense of scale, at https://www.missingkids.org/gethelpnow/cybertipline/cybertiplinedata https://www.missingkids.org/gethelpnow/cybertipline/cybertip... > The CyberTipline receives reports from the public and online electronic service providers (ESPs). ... U.S. based ESPs are legally required to report instances of child sexual abuse material (CSAM) or “apparent child pornography” to the CyberTipline when they become aware of them, but there are no legal requirements regarding proactive efforts to detect CSAM (Reports are also in various other categories aside from CSAM.) > In 2022, NCMEC staff escalated over 49,000 reports to law enforcement as the reported incident was urgent in nature or there was information that a child was in imminent danger. ... NCMEC designated 49% of the reports from the tech industry as “actionable” when referring them to law enforcement in 2022 (49000 is a heavily filtered fraction of the 32 million total reports.)
