They should just unleash Old School Troll Prince Philip

Royal Family threaten to block and report social media trolls to police as they issue new rules in wake of racist and sexist abuse

The Royal Family has published rules for followers of its social media channels, warning that anyone who posts offensive comments will be blocked or reported to the police in the wake of escalating abuse of the Duchesses of Cambridge and Sussex.

The Royal Family has issued guidelines on social media to create a “safe environment” on its Twitter and Instagram channels, urging “courtesy, kindness and respect”.

Anyone who posts obscene, offensive or unintelligible content now runs the risk of being deleted, blocked or subject to legal proceedings in the most significant measures yet to protect the mental health and wellbeing of followers.

Philip would be a star on twitter.
