1. Trusted, centralised sources like the Economist, BBC, NYTimes, etc.
2. Everything else, you should basically assume is generated information pushing some agenda.
Quoting some stats from an article on HN mid last year (links to sources didn't copy over) [1]
---------------------------------
* Elon Musk estimates that 20% of Twitter users are bots. The authors of this paper suggest 14% as an upper bound.
* Supposedly 10% — or around 95m — of accounts on Instagram are bot/spam accounts.
* In a study of the first impeachment of Donald Trump (same paper as linked above), bots made up 1% of active users, but posted 31% of the tweets.
* Some 42% of Amazon reviews are fake. Amazon are suing Facebook for ‘failing to tackle fake review factories’
* TikTok is not immune either. Bots are artificially inflating popularity of accounts and posting videos that are essentially adverts. Here’s a comprehensive guide to buying bots on TikTok.
* According to this article, “over 80 percent of NFTs minted for free on OpenSea are fake, plagiarised or spam”.
---------------------------------
For any platform where any user is free to create their own content. In the not too distant future, nine times out of ten, they'll be a bot.
