Social media firms have been warned by the UK government that they could face hefty fines if they fail to remove harmful content quickly.
The government is seeking to improve online safety through a new bill announced in the Queen's Speech earlier this week, and Digital Secretary Oliver Dowden has welcomed the introduction of the "ground-breaking laws".
It's hoped that the move will lead to "a new age of accountability for tech".
On the other hand, some campaigners have already questioned the new legislation, suggesting it's too vague and not strong enough.
Tech entrepreneur Belinda Parmar told the BBC: "The ambition is great. The regulator is going to have teeth, but no codes of practice for non-legal harms have yet been published, and it is all very vague."
Sir Peter Wanless, chief executive of the NSPCC, has also questioned the new legislation.
He said: "Government has the opportunity to deliver a transformative online safety bill if they choose to make it work for children and families, not just what's palatable to tech firms.
"The ambition to achieve safety by design is the right one. But this landmark piece of legislation risks falling short if Oliver Dowden does not tackle the complexities of online abuse and fails to learn the lessons from other regulated sectors."
