The previous poster isn't definitively stating there is legal liability - but they are setting the stage and providing evidence as to why such liability might be legally considered. It isn't the job of internet commentators to litigate - and, Facebook is one of the rather new cohort of companies involved with social media on a global scale. There have been cases in the past when local social clubs and media outlets have incited violence - but nothing of this scale exists in precedent to my knowledge because this is an entirely novel scale. I'd also mention that there AFAIK was no intentional effort on Facebook's part to make the situation worse specifically - but building a system that causes harm can cause liability even if that harm is unintended. No factory owner ever intended for their employees to lose limbs in heavy machinery, but they have been repeatedly held liable for it. I personally think the case against Facebook is weak - but I am certainly aware that I don't have nearly enough visibility on the internals to make any sort of definitive statement.
