"Just weeks after a broad effort announced by tech platforms to curb the spread of violent content, a video of Wednesday's deadly shooting in the German city of Halle was posted online, where it was seen by some 2,200 people. Hans-Jakob Schindler of the Counter Extremism Project, a group seeking to curb online violence, said the latest livestream highlights a need for stronger actions against social platforms. 'Online platforms need to step up and stop their services being used and in turn, parent companies need to hold them accountable,' Schindler said. 'Amazon is just as much to blame as Twitch for allowing this stream online. This tragic incident demonstrates one more time that a self-regulatory approach is not effective enough and sadly highlights the need for stronger regulation of the tech sector.'"
