People using Netflix, Amazon Prime Video or Disney Plus are being issued a stark warning.
It has been ruled that password sharing is illegal, which means millions of people may be breaking the law. The Intellectual Property Office (IPO), which has published the new guidance in conjunction with the Facebook and Instagram owner Meta, has issued the ruling.
The IPO said: "Piracy is a major issue for the entertainment and creative industries. Pasting internet images into your social media without permission, or accessing films, TV series or live sports events through Kodi boxes, hacked Fire Sticks or apps without paying a subscription is an infringement of copyright and you may be committing a crime."
