It’s clear that nefarious regimes have won on social media.
It would be interesting to understand the ratio of real human posts to manipulation on twitter for example - I’d imagine it has long ago tipped to majority bot.
Tackling this problem is existential for western democracies. This seems like a reasonable idea. There might be other options (like validated but anonymous) but we have to try something.
It’s worth noting too that many strong western democracies have laws around hate speech and libel that are being broken by anonymous people online - and the citizens of those countries are perfectly happy with those laws.
