The topic of discussion is shadow banning which is different from flagging. It is applied by the website automatically, displaying [dead] rather than [flagged]

There are several [dead] comments in this comment section even though there's nothing wrong with them.

Maybe, you don't know that. However, we constantly see stuff getting "flagged" on here that is totally fine, like this question we're on.

Only content that goes against the law or the site's guidelines should get flagged, not opinions or articles that aren't to the liking of some folks.

Liberality also means putting up with opinions that don't suit you.
