(Wired) Videos of children showing their exposed buttocks, underwear and genitals are racking up millions of views on YouTube – with the site displaying advertising from major cosmetics and car brands alongside the content.

Comments beneath scores of videos appear to show paedophiles sharing timestamps for parts of the videos where exposed genitals can be seen, or when a child does the splits or lifts up their top to show their nipples. Some of the children in the videos, most of whom are girls, appear to be as young as five. Many of the videos have hundreds of thousands, if not millions of views, with hundreds of comments.

The videos are also being monetised by YouTube, including pre-roll adverts from Alfa Romeo, Fiat, Fortnite, Grammarly, L’Oreal, Maybelline, Metro: Exodus, Peloton and SingleMuslims.com. Banner advertising for Google and the World Business Forum also appeared alongside some of the videos. As well as providing YouTube with our research, we contacted the advertisers to alert them to the issue.
