Somebody mentioned it the other day, and it rings true; social media is dramatically under-regulated. For all intents and purposes, it's a lawless battleground where people can say what they want and face zero repercussions; in the name of upholding free speech, of course.
Absolutely. Where the amount a message is amplified isn't dependent on how accurate it is, but on the personality who is mentioning it.
Interesting novel I read a while back, 'The Circle' - a near-future society that had moved to one form of social network and where people had to use their true identity. Things still go wrong, obviously, but I think it would be a start. So much of the disinformation that is in place is from automated bots, get rid of them and things would instantly improve to an extent.
