Surveys have shown some younger Americans believe the Holocaust was a myth or has been exaggerated.
Tech companies began promising to take a firmer stand against accounts used to promote hate and violence after a 2017 rally in Charlottesville, Virginia, where a self-described white supremacist drove into a crowd of counterprotesters.

Yet Facebook and other companies have been slower to respond to posts that amplify misinformation, but don't pose an immediate threat of violence or other physical harm.
Zuckerberg said in a blog post Monday that he believes the new policy strikes the “right balance” in drawing the lines between what is and isn't acceptable speech.
“I’ve struggled with the tension between standing for free expression and the harm caused by minimizing or denying the horror of the Holocaust,” Mark Zuckerberg wrote.
“My own thinking has evolved as I’ve seen data showing an increase in anti-Semitic violence, as have our wider policies on hate speech."
Zuckerberg had raised the ire of the Claims Conference, based in New York, and others with comments in 2018 to the tech website Recode that posts denying the Nazi annihilation of 6 million Jews would not necessarily be removed.
He said he did not think Holocaust deniers were “intentionally” getting it wrong, and that as long as posts were not calling for harm or violence, even offensive content should be protected.
