Sending “genuinely threatening” or “knowingly false” messages are among new criminal offences being added to proposed online safety laws, according to BBC News.
If passed, the government’s online safety bill could see social networks fined 10% of their global turnover if they fail to remove harmful content.
The changes mean they will also have to proactively remove harmful content.
The bill also covers revenge porn, human trafficking, extremism and promoting suicide online.
It already stated that websites, such as Facebook and Twitter, that host user-generated content would have to swiftly remove illegal content once it was reported to them.
Now they will also have to put in place proactive measures to stop illegal activity.
