Online grooming – where an adult builds trust with a child online in order to exploit or abuse them – is one of the most common and most misunderstood online harms. Two platforms feature in case after case: TikTok and Snapchat. This updated guide (October 2026) explains how grooming works on each app, the signs to look for, and the practical steps that protect children.
The scale of the problem
NSPCC research suggests more than 200,000 secondary school children in the UK may have been groomed online. Around 4% of 11 to 17-year-olds surveyed had sent, received or been asked to send sexual content to an adult – most often via Snapchat, Facebook and Facebook Messenger (1 in 25 children), then Twitch and Twitter (1 in 33) and Instagram and WhatsApp (1 in 50). Groomers typically make first contact on public features, then move children to encrypted or disappearing-message apps. (Source: NSPCC)
Grooming on TikTok: how it works
TikTok’s design – algorithmic feeds full of strangers, public comments, LIVE streams with gifting, and direct messages – gives groomers a clear pathway:
- Friendly public contact on a child’s videos: compliments, shared interests, sympathy.
- A move to private channels – TikTok DMs, then often Snapchat or an encrypted app where content disappears.
- Trust-building through flattery, gifts (including TikTok LIVE gifts) and lying about their age.
- Requests and secrecy – photos, videos, and pressure not to tell parents, which can escalate into sextortion.
Regulators are paying attention. Ofcom opened an investigation in July 2026 into TikTok’s compliance with its duties to protect children (Source: Ofcom), and an October 2026 NPR investigation reported that TikTok staff had raised child safety concerns internally (Source: NPR).

Grooming on Snapchat: how it works
Snapchat appears in grooming reports so often because of how the app is built:
- Disappearing messages remove evidence and encourage risk-taking – groomers explicitly exploit this.
- Snap Map can reveal a child’s live location unless Ghost Mode is on.
- Quick Add and Snapstreaks normalise contact with strangers and create daily pressure to keep responding.
This short explains Snapstreaks and why they matter:
Warning signs
- Secrecy about online contacts; switching screens when an adult approaches
- Unexplained gifts, money or in-game currency
- More time online, especially late at night
- An older “friend” nobody has met
- Distress or withdrawal after being online
- Age-inappropriate knowledge of sexual behaviour
Prevention: what works
- Keep talking. Ask regularly which apps they use and whether anyone online has asked them to keep secrets, move apps, or send images.
- One family rule: only chat online with people known and trusted in real life.
- Lock down settings: private TikTok account with DMs limited; Snapchat Ghost Mode on and contact restricted.
- Respond calmly. A child who fears anger will hide problems. Curiosity keeps the door open.
- Repeat that it is never the child’s fault.
If you suspect grooming
- Screenshot everything before it disappears.
- Report the account to the platform and keep evidence of the report.
- Block the account.
- Report to police – in the UK, also to CEOP (ceop.police.uk).
- Reassure the child they did the right thing.
