Facebook, Twitter, and Chinese-owned TikTok face fines of up to 10% of turnover if they fail to remove and limit the spread of illegal content under laws proposed by Britain on Tuesday.

Axar.az reports that tech platforms will also need to do more to protect children from being exposed to grooming, bullying, and pornography, the government said, to ensure the safety of children online.

“We are entering a new age of accountability for tech to protect children and vulnerable users, to restore trust in this industry, and to enshrine in law safeguards for free speech,” Britain’s Digital Secretary Oliver Dowden said.

Governments are wrestling over measures to better control illegal or dangerous content on social media, with the European Union set to unveil its own package on Tuesday.

Britain’s new rules, which will be introduced in legislation next year, could lead to sites that break the rules being blocked and senior managers held liable for the content.

Popular platforms will be required to have clear policies for content that, while not illegal, could cause harm such as disseminating misinformation about COVID vaccines.

Dowden said the framework would give large digital businesses “robust rules” to follow.
