Need to Report Photographer for a series of inappropriate photos

How do I report a photographer for inappropriate photos of a girl who is clearly a teenager in positions wearing either nothing or almost nothing? She's dressed to look young too (schoolgirl, etc) in these positions. It's highly inappropriate.

I made the mistake of looking up "teenage girl" when I was looking for an image for an advertising campaign I'm working on, and those images came up. Awful. Would never expect to see something like that in the Adobe Stock catalog that I'm searching on my work computer.
