Kim Kardashian West and dozens of other celebrities have frozen their social media accounts for 24 today to protest against the spread of hate, propaganda and misinformation.
The move is part of the #StopHateforProfit campaign which was organised by civil rights activists.
Other celebrities that have taken part in the boycott include actors Ashton Kutcher and Leonardo DiCaprio plus singer Katy Perry.
The organisers of the #StopHateforProfit campaign accuse Facebook and Instagram of not doing enough to stop hate speech and disinformation.
