The social media giant said the measure aims to protect young users and ensure safer online experiences while it reviews ways to monitor and manage content more effectively.
According to TikTok, the restriction affects live broadcasts taking place during late-night hours, when the platform noted an increase in sexually explicit material.
The company explained that this step is necessary to address the problem and reduce exposure to inappropriate content, particularly for minors who may be online at those hours.
The decision comes after reports and complaints from parents, educators, and digital safety organizations highlighting the risks of unchecked sexual content on social media.
Experts say such content can influence young users negatively, affecting their mental and emotional well-being.
TikTok acknowledged these concerns and said it is committed to maintaining a safe environment for all users.
TikTok emphasized that the temporary ban is not a permanent measure. Instead, it allows the platform time to implement stronger content moderation systems and improve monitoring of live streams.
The company said it is exploring new technology and stricter guidelines for creators to prevent the sharing of sexually explicit material during high-risk hours.
In addition to the late-night restriction, TikTok urged Nigerian users to report inappropriate content and reminded creators to follow community guidelines.
The platform said user reports are a key part of keeping the app safe, especially for younger audiences.
Digital rights groups have welcomed the move, describing it as a necessary step to protect minors while encouraging responsible use of social media.
At the same time, some users have raised concerns that the restriction may affect genuine content creators who broadcast educational or entertainment programs at night.
