TikTok is raising its minimum age for livestreaming from 16 to 18 from next month.
A BBC News investigation found hundreds of accounts going live from Syrian refugee camps, with children begging for donations.
Some were receiving up to $1,000 (£900) an hour – but when they withdrew the cash, TikTok had taken up to 70%.
In future, only adults would be able to “send virtual gifts or access monetisation features”, TikTok said.
And, “in the coming weeks”, it would let users run adult-only livestreams.
It is unclear how TikTok will enforce these age restrictions, however.
Meta, which owns Facebook and Instagram, and Google, which owns YouTube, have a minimum livestreaming age of 13 and already allow users to age-restrict content they upload.
TikTok’s rules say you must not directly solicit for gifts and must “prevent the harm, endangerment or exploitation” of minors on the platform.
TikTok said this type of content was not allowed on its platform and its commission from digital gifts was significantly less than 70% but still has not confirmed the exact amount.
