This is a really good point, and this sort of thing could well be happening already. There has already been controversy over negative posts related to immigration being removed from Facebook due to a deal with the government. And there's already been talk of people inside Facebook asking whether they're 'doing enough' to stop a Donald Trump presidency: http://gizmodo.com/facebook-employees-asked-mark-zuckerberg-if-they-should-1771012990 http://gizmodo.com/facebook-employees-asked-mark-zuckerberg-... As well as cases where people were visited by police after making right wing comments online: http://www.breitbart.com/london/2016/04/07/police-raid-social-media-posts/ http://www.breitbart.com/london/2016/04/07/police-raid-socia... (Yes, I know it's from Breitbart, but the point still stands) And there's a lot of talk about Twitter censorship, blockbots blocking people based on what accounts they follow rather than any actions and all that stuff. Similar systems are already being abused by social networks, and this type of technology will only make cases like this more common.
