@kirstyyarr Before I left Facebook, I owned a page with about 120k likes. The flamewars in the comments were, honestly, nastier than anything I've seen on any other platform. My neighborhood group (!) was almost as bad. Lack of anonymity extending to *knowing where you live* was no deterrent to abusive behavior.
but they also have access to specialist CSI who can seize/inspect computer data, cellbrites and other such boxes (to get data from mobile phones when required), and at least /some/ level of co-operation from the USA based corporate social networks to hand over data without too many obstacles.
Everyone here is focused on GCHQ/MI* etc so often overlooks the rôle of "normal" cops (its not even a secret thing and is regularly reported in local news)
