I was shadow banned, I was redpilling on facebook for 2.5 years, always stirred shit up, always got reply chains that dragged on to other topics.. then in 2020 around Sept/Oct, suddenly no one ever responded to me.. checked from a friends account, sure enough, 90% of my comments on certain pages (like politicians pages and CNN page) couldn't be found even though I could see them.
