After reading it, I’m still unsure what all they consider to be CSAM and how much of each category they found. Here are what they count as CSAM categories as far as I can tell. No idea how much the categories overlap, and therefore no idea how many beyond the 112 PhotoDNA images are of actual children.
112 instances of known CSAM of actual children, (identified by PhotoDNA)
713 times assumed CSAM, based on hashtags.
1,217 text posts talking about stuff related to grooming/trading. Includes no actual CSAM or CSAM trading/selling on Mastodon, but some links to other sites?
Drawn and Computer-Generated images. (No quantity given, possibly not counted? Part of the 713 posts above?)
Self-Generated CSAM. (Example is someone literally selling pics of their dick for Robux.) (No quantity given here either.)
