This is a major problem for all democracies, and LLM driven troll accounts probably do exist. But this xitter post is a fake error message. It’s clearly a troll.
Blocking fake accounts would help with the misinformation problem, but it’s a cat and mouse game. It could ultimately give additional credence to the trolls who slip through if the platform is assumed to be safe. The reality is that there will always be ways for fake accounts to avoid detection and to spoof account verification. Making it harder would help, but it’s not a comprehensive solution. Not to mention the fact that the platform itself has the power to manipulate public opinion, amplify their preferred narrative, etc.
The solution I’ve always preferred is the mentality the 4chan community had when I was younger and frequented it. Basically, and I’m paraphrasing:
Everyone here needs to grow up and understand that no post should ever be presumed to be true or legitimate. This is an anonymous forum. Assume that everything was written by a bot or a troll in the absence of proof that it wasn’t.
I think people put too much trust in social media precisely because they assume that there’s a real person behind every post. They assume that a face and a few photos gives an account legitimacy, despite the fact that it’s trivial to copy photos from a random account (2015/16 pro-Trump Facebook style) or just generate all of the content from scratch with AI (to avoid duplicate detection).
Trust itself is driver of misinformation. On social media, people should only fully trust posts made by people they know. That is the simplest and most comprehensive solution to the problem.
