CEP Executive Director David Ibsen writes: "Brussels-based think tank Centre for European Policy Studies and the Berlin office of the international organization, Counter Extremism Project (CEP) have teamed up to study this NetzDG law, seeing it as a key test for combating extremist online speech. Under the NetzDG, which came into effect at the beginning of 2018, online platforms with more than two million German users face up to €50 million fines if they do not remove “blatant illegal” hate speech and other postings within 24 hours of notification. At the same time, the goal of eradicating extremist content from the Internet remains far off. Just recently, the Counter Extremism Project released a study that shows YouTube’s efforts to proactively remove ISIS terrorist content is failing. Some 91 percent of ISIS videos studied were uploaded more than once; 24 percent of terrorist videos remained online for more than two hours. YouTube is losing this game of whack-a-mole with ISIS campaigners. Additional measures are required to fight this alarming phenomenon."
