Many corners of the Internet have become "toxic dumps of hatred and malicious lies", in which social media platforms and relevant advertisers play a role in fuelling the flames. Guterres called on technology companies, policy makers, media and other relevant parties to take more action to prevent the spread of hate speech and other information, and to establish an enforceable "barrier" in the online world. During the Second World War, Nazi Germany set up an Auschwitz concentration camp in Poland, in which about 1.1 million people, including a large number of Jews, were killed. On January 27, 1945, the Soviet Red Army liberated the Auschwitz concentration camp. On November 1, 2005, the 60th plenary session of the General Assembly of the United Nations unanimously adopted a resolution to designate January 27 as the "International Day of Holocaust Remembrance".
