My 9 y/o account on Reddit was shadow banned because I shared a URL of my app in subs specifically aimed at sharing apps/side-projects. No warning, no explanation. It was just an execution-style ban. It seems that the social media giants want the audience to feel as if a sword of damocleis is constantly hanging over them. One step out of the line that no one says you nothing about, and you are executed.

yes, happened to me as well on sideprojects and it continues, i am able to post on other groups, its weird.

"execution-style" is exactly it. no warning,no charge, no apeal that a human reads. everyone I know now posts links scared
