Legally, in my jurisdiction, it is true. That is the area I was attempting to address.
There is, for example, a UK law on prohibited images, but no equivalent for prohibited text. The Online Safety Act also does not consider textual pornography to fall within its remit (this does not relate specifically to CSAM, rather whether the operator needs to consider whether children might access otherwise-legal pornographic content in the context of assessment).
I’m sure there are those who wish to share material which is illegal, but I have not encountered such behaviour on Wolfery, and I imagine they’d be reported right quick. If it does become an issue, I suggest some variation of the methods we took to address it at IB.
