Auschwitz survivors around the world welcome Mark Zuckerberg's decision to ban Holocaust denial from Facebook pages in the future. In view of the worldwide influence of Facebook, but also in view of the number of users, this is a long overdue decision for them. In Warsaw, the Auschwitz survivor and IAK Vice President Marian Turski emphasised: "I recently sent an open letter to Mark Zuckerberg and urged him to ensure that his life's work is no longer devalued with the filth of Holocaust deniers: I am grateful that he has taken this decision". And in Berlin, Christoph Heubner, Executive Vice-President of the International Auschwitz Committee, added: "In view of the worldwide propensity for violence of anti-Semites and extreme right-wing hate preachers, this decision is of great symbolic importance. Holocaust deniers will no longer be able to spread their lies and hatred via Facebook. It is good that Mark Zuckerberg has finally realised the importance of his power and the verbal and real existence of right-wing extremist and anti-Semitic hatred after all."
