Internet groups such as Facebook, Google’s YouTube and Twitter need to do more to stem the proliferation of extremist content on their platforms, the European Commission said after a meeting on Wednesday. The Counter Extremism Project (CEP), a non-profit organization, said efforts by the companies were encouraging but did not make a strong case for continued self-regulation. “Instead, what the EU Internet Forum should aim to deliver are concrete, industry-wide policies on blocking or rapidly removing illegal content and consistent enforcement of those policies,” said David Ibsen, Executive Director of the CEP.”
