Under the revised Online Safety Bill, providers that publish or place pornographic content on their services will have a legal duty to prevent children from accessing that harmful content. To this end, robust checks must be implemented to ensure their users are 18 years old or over, including by using age verification technologies. If sites fail to act, the independent regulator Ofcom will be able fine companies up to 10 per cent of their annual worldwide turnover or can block them from being accessible in the UK. Bosses of these websites could also be held criminally liable if they fail to cooperate with Ofcom.
