Why is there borderline CP in stock photos?

So I'm doing a project for school telling a story involving a child growing up and was looking for stock footage of kids to use. I typed in "young kid" to start with and the results were a bit off putting.

You have a few normal photos but then there are a bunch that emphasize kids feet, kids with their mouth gapping open, and some with little girls showering. I mean if it was maybe one or two I wouldn't think anything of it but its A LOT.

The first page alone had 26 pictures of little girls feet for instance and 13 of their mouths gaping open. I checked the second page and it was more of the same but I didn't want to count it.

Of course, a image by itself of a little girl's feet means nothing but when its a lot like that its incredibly fucking gross. I organized it by "relevance" and "exclude AI" so they're real videos. My question is why so many? What gives? Its really gross.
