Discord is probably still dependent on PDNA (a valuable industry standard LLM tool) for its “first pass”look at newly uploaded content. When I worked there, it was the daily job of one person (me btw just me it was only me) to look through what PDNA flagged as potentially CSAM, and to then tell it yes/no; if I said “yes” the account that uploaded it would be immediately locked, and the image or video reported to the authorities. PDNA is an image hash matching system, which essentially means it views media in a grid pattern and looks for things it recognizes within the sections of that grid. As such, it was very common to see innocent grid patterns, screenshots of video game inventories, and checkerboard style images to show up in the matching. Now, an image just showing up in the matching in no way means (meant?) that it was CSAM, or suspected to be CSAM, just that something in the grid triggered PDNA’s hash match. My job, then, was to confirm if it was correct.
