Twitter has suspended several accounts that have been set up to share posts from Donald Trump’s website.
The micro-blogging site said the accounts broke the rules by helping the former president to circumvent a ban from the social network.
Mr Trump was banned from a number of platforms after his supporters stormed the US Capitol on 6 January
Twitter, where he had 88 million followers, has said its ban is permanent, regardless of whether or not Mr Trump runs for office in future.
Facebook upheld its own ban on Wednesday, and YouTube said it will restore the former president’s channel when the risk of violence has decreased.
But also this week, Mr Trump added a page to his personal website which he called “From The Desk Of Donald J Trump”.
The accounts suspended by Twitter included @DJTDesk, @DJTrumpDesk, @DeskofDJT and @DeskOfTrump1.
