What triggers it
Claims that a verified mass-casualty event (the Holocaust, school shootings, terrorist attacks, natural disasters) did not happen, or that victims are 'crisis actors', shared in an abusive context.
What X says
“We prohibit content that denies that mass murder or other mass casualty events took place, where we can verify that the event occurred, and when the content is shared with abusive context.”

How to fix it

Good to know
Look for 'hoax', 'false flag', 'crisis actors' or 'it never happened' about named real events, especially when victims or survivors are mocked or called fake. Does NOT count: questioning death tolls, official accounts or how authorities handled the event without denying it happened, or fiction clearly presented as fiction.
