A key element was to retrain its company’s AI video detection systems by feeding it a dataset of harmful content, to work out what to highlight and block. It also details how Facebook grappled with the problem, trying to improve its cutting edge technology.

The leaked documents, initially published by Gizmodo, underscore the failure, showing that at the time of Christchurch, the social media giant was “only able to detect violations five mins into a broadcast” – and that the attack video only scored 0.11 on an internal graphic violence scale when the threshold for intervention was 0.65. No Facebook user complained for 29 minutes and executives were forced to admit its detection systems were “not perfect”. “Since this event, we’ve faced international media pressure and have seen regulatory and legal risks increase on Facebook increase considerably.”Īt the time Facebook admitted its AI systems had failed to prevent the broadcast, and the video was only removed after the company was alerted by New Zealand police.
