Kim Kardashian West and dozens of other celebrities have announced they will freeze their social media accounts to protest against the spread of "hate, propaganda and misinformation".
"Misinformation shared on social media has a serious impact," Kardashian West wrote in a statement on Tuesday.The move is part of the #StopHateforProfit campaign which was organised by civil rights activists.
The celebrities will freeze their accounts for 24 hours on Wednesday.
"I can't sit by and stay silent while these platforms continue to allow the spreading of hate, propaganda and misinformation - created by groups to sow division and split America apart," Kardashian West said.
"Misinformation shared on social media has a serious impact on our elections and undermines our democracy," she added.
Other celebrities that have agreed to take part in the boycott include actors Leonardo DiCaprio, Sacha Baron Cohen and Jennifer Lawrence, as well as singer Katy Perry, BBC reported.
The group has focused on Facebook, which also owns Instagram and WhatsApp and last year attracted advertising revenue of almost $70bn (£56.7bn).Thousands of businesses and major civil rights groups - including the National Association for the Advancement of Colored People (NAACP) and the Anti-Defamation League (AD) - have signed up to the campaign.
Founder Mark Zuckerberg also said the social media company would ban advertising containing claims "that people of a specific race, ethnicity, national origin, religious affiliation, caste, sexual orientation, gender identity or immigration status" are a threat to others, BBC reported.
