WSJ created Instagram accounts following only young gymnasts and influencers and found salacious Reels, like risqué footage of kids, shown next to big brand ads
Content served to WSJ test accounts included risqué footage of kids, overtly sexual adult videos and ads from major brands
Context & Ripple Effects
The test adds a brand-safety and child-safety dimension to earlier reporting on Instagram’s teen strategy: internal materials had already put the platform’s effects on teen girls under scrutiny in the WSJ’s publication of internal Instagram documents. The concern is not simply that problematic videos exist, but that recommendation systems can place them in feeds built around young users and alongside paid advertising.
The pattern also persisted in later testing: accounts listing an age of 13 were still recommended sexual videos on Instagram, unlike comparable tests on Snapchat and TikTok in a later comparison of teen-account recommendations.
First-order effects
- Instagram and its advertisers face an immediate placement-risk problem: major-brand ads appeared adjacent to sexualized material, including risqué footage involving children.
- The findings put pressure on Instagram’s Reels recommendation and ad-suitability controls, particularly for accounts whose follows signal interest in young gymnasts or influencers.
Second-order effects
- Brands and agencies have reason to demand tighter exclusion, reporting, and placement controls for Reels inventory rather than treating platform-level safety policies as sufficient.
- Rival platforms can differentiate their short-video ad products on demonstrable protections for teen-facing recommendation feeds; the later comparative test gives that claim a concrete benchmark against Instagram’s teen-account results.
Third-order effects
- If repeated audits continue to find unsafe recommendations despite moderation efforts, child-safety enforcement will increasingly be evaluated at the level of ranking and ad adjacency, not only whether individual posts are removed.
- The case points to a broader mismatch in engagement-led short-video systems: content that attracts attention can create risks for minors and advertisers at the same time, forcing platforms to make safety controls measurable to outside stakeholders.
The trend: Short-video platforms are moving toward greater accountability for how recommendation engines and ad delivery jointly shape child safety and brand suitability.
