Why are children's safety groups calling for age verification on porn sites?
They fear it is too easy for children to access publicly available pornography online. Experts who work with children say pornography gives children unhealthy views of sex and consent, putting them at risk from predators and possibly stopping them reporting abuse.

It can also lead to children behaving in risky or age-inappropriate ways, harming themselves and others. Charities say children tell them that pornography is difficult to avoid and can leave them feeling ashamed and distressed. One concern is the extreme nature of porn on mainstream sites, with one study showing that one in eight videos seen by first-time visitors showed violent or coercive content.
