Whistleblower Khaled Hassan started work at Crisp, a Leeds-based "digital risk intelligence" firm employed to moderate content for YouTube, in February 2021. As an Egyptian-born Arabic speaker, his job was to identify hateful content in his native language and flag it to the video sharing giant to be removed. But he soon realised that getting the company to take down antisemitic videos and those that glorify terrorism was not going to be easy, despite YouTube's policies claiming it will do so.
