You're really mad that a US based study is using the US definition of CSAM while also clearly stating the definition of CSAM they're using, aren't you?
Sure buddy, it's a "false equivalence", they're totally stating it's the same. It's not just your reading comprehension
I don't believe you're physically capable of self-consistently stating what you think your point is. You're somehow not equating these things you just said are defined as the same thing. You're sneering as if noticing that definition - which you block-quoted - is some kind of delusion.
All while projecting emotion in a way that's almost as ironic as your constant parroting of the phrase "reading comprehension."
Is it difficult to use the internet without object permanence?
