A BBC investigation found what appear to be children exposing themselves to strangers on the Omegle live video chat website.
The site claims to be moderate and has exploded in global popularity during the pandemic with millions of visitors per day, particularly in the US, India, Mexico and the UK.
It has become a TikTok trend, frequently visited by children, and international protection groups are increasingly concerned that predators are using Omegle to collect so-called "self-generated" abuse material.
The founder of the website, Leif K-Brooks, told the BBC that his site has increased moderation efforts in recent months.
TikTok claims it has now banned the sharing of links to Omegle and that its security teams have not found any malicious Omegle content on its platform.
