LONDON: The Royal Family has published social media guidelines for the public, vowing to block users who leave offensive or abusive comments on official channels.
It follows reports that staff have been battling a surge in abuse aimed at the Duchesses of Cambridge and Sussex.
Neither of the duchesses have personal social media accounts.
Meghan closed down hers last year, before marrying Prince Harry.
In December 2017, shortly after her engagement, she had 1.9 million people following her posts on Instagram, and more than 350,000 Twitter followers. Her Facebook page had almost 800,000 likes.
Some of the worst, hate-filled personal abuse directed at the Royal Family’s various social media accounts is said to come from rival fans of Kate and Meghan.
The new rules call for comments not to “contain spam, be defamatory of any person, deceive others, be obscene, offensive, threatening, abusive, hateful, inflammatory or promote sexually explicit material or violence”, or “promote discrimination based on race, sex, religion, nationality, disability, sexual orientation or age”.
The Royal Family said the guidelines were introduced to maintain “a safe environment” on channels run by the three households, and called for users to show “courtesy, kindness and respect”.
The statement adds: “We reserve the right to hide or delete comments made on our channels, as well as block users who do not follow these guidelines. We also reserve the right to send any comments we deem appropriate to law enforcement authorities.”
The official Twitter account of the Duke and Duchess of Cambridge, the Duke and Duchess of Sussex and their Royal Foundation, has almost 1.7 million followers, while their Instagram account boasts 7.1 million.
The Royal Family has 3.8 million followers on Twitter, 4.5 million on Instagram, and its Facebook page has 4.8 million likes, while Clarence House has 812,000 followers on Twitter and 624,000 on Instagram.
The Duke of Cambridge has been a prominent campaigner against cyber-bullying, and has previously accused social media giants of being “on the back foot” when it comes to fighting issues like online bullying, fake news and hate speech.
In 2017, he convened a new industry-led taskforce to develop a shared response to the online bullying of young people.
