Not so much these days. But back in the day one of the crude efforts to control access to porn on the internet was filtering for the word "porn", which lead to a standard mis-spelling of it as "pr0n". Which became so ingrained that I now spell it that way by default.
I was mostly referencing that rather than trying to avoid an actual filter now.
"Child pornography" is very specifically-defined in terms of strictly-photorealistic content.
Notice that the topic discussed here is chat control. What does this have to do with photorealistic content?
The "CSAM" moniker is a broad net that drags other forms of media into scope. Sharing a fictional story about raping a child isn't child pornography (there's no victim)...but it is CSAM.
Same with manga/comics, sharing elaborate fantasies, AI images and any other fictional products. As CSAM, all of it becomes fair game for indictment.
Groups pushing to call child pornography CSAM push to ban fictional media also. But people were prosecuted for virtual child pornography before. The groups justify the new term saying all child pornography depicts child sexual abuse. And people talk about virtual CSAM.
