While it can be difficult/impossible to draw the line based on appearances, these were clearly and obviously
Ugh. Why am I not surprised?
I think there's a discussion to be had about questionable porn, like I mentioned in a comment above someone like Piper Perri (of sitting on a couch with black guys behind her meme fame) is nearing thirty. I get that people wouldn't want something featuring an actress like her in their feed because she looks younger, but I also get why people would find it draconian to ban it as she is an adult woman.
But you can't really have a nuanced discussion on where to draw the line, and end up having to err on the side of caution, because of the creeps.
Reminds me a bit of discussing free speech or Israel. There are nuances, and the line is blurry, but nuanced discussion is impossible, because before you know it you're agreeing with someone with a swastika tattoo on his forehead.
