The BBC Eye investigation has uncovered paid advertisements on Instagram, a popular social media platform, promoting child sexual abuse material in India. These ads use explicit language and link users to Telegram channels where such content can be purchased for as low as 99 rupees (approximately $1). Although Instagram's moderation technology reviews all ads before publication, the BBC found that an advert reporting one of these ads was not removed until 24 hours later. Meta, Instagram's parent company, responded by disabling several adverts and suspending the accounts posting them after being contacted by the BBC. However, Telegram has reported removing over 274,000 groups and channels related to child sexual abuse material in 2026. To investigate further, the BBC created an alias account on Instagram, which began following women posting suggestive content despite no search for such material. This new account was soon bombarded with advertisements featuring adult pornography and children in sexually suggestive situations, linked to Telegram channels. Adverts promoting child sexual abuse were seen about 30 times, with some being shared by multiple accounts. The distribution of both child sexual abuse material and adult pornography are criminal offenses in India, while Meta's policy prohibits such content in ads. The BBC reported all the ads and the Telegram channels to the Indian authorities. Critics have previously accused these platforms of not doing enough to prevent the sharing of criminal content, with Telegram, a Dubai-based company, being non-member of organizations like the National Center for Missing and Exploited Children and the Internet Watch Foundation. Despite ads being a significant source of income for Meta, the company claims every advert is reviewed before publication. However, the system primarily relies on automated technology and may not detect all policy violations.
