TikTok is profiting from sexual livestreams performed by teens as young as 15, the BBC has been told.

BBC spoke to three women in Kenya who said they began this activity as teenagers. They told us they used TikTok to openly advertise and negotiate payment for more explicit content that would be sent via other messaging platforms.

TikTok bans solicitation but the company knows it takes place, moderators have told the BBC. TikTok takes a cut of about 70% from all livestream transactions, we have previously found.

TikTok told the BBC it has "zero tolerance for exploitation".

Livestreams from Kenya are popular on TikTok - each night over the course of a week, we found up to a dozen in which women performers danced suggestively, watched by hundreds of people around the world.
