The Dead Internet Theory
i.e. Most of The #Internet is Fake
"The Dead Internet Theory is the belief that the vast majority of internet traffic, posts and users have been replaced by bots and AI-generated content, and that people no longer shape the direction of the internet.
The theory was floating around #4Chan in the late 2010s, but it was solidified and amplified in 2021 after a lengthy post describing the theory was posted on a thread titled " #DeadInternetTheory: Most Of The Internet Is Fake " on the forum Agora Road's Macintosh Cafe."
