Following up on #trustcon23, I wrote about how a thriving trust and safety vendor ecosystem has emerged, despite difficult headwinds for the industry as a whole. https://techpolicy.press/the-evolving-trust-and-safety-vendor-ecosystem/
Interesting tidbit from Meta staff at #TrustCon23 just now: >90% of the CSAM Meta report to NCMEC is visually similar to content they’ve reported before.
The argument goes: The same bad content circulates again and again, so effective moderation requires you to get very good at similarity detection.
