When moderators weren't just deleting it as soon as it was flagged (because they were on strike or had resigned), a lot of the threats, shunning and general cruelty were publicly visible on mSE. And that was with normal users still successfully instructing the system to remove them (I won't go into technical details).

A person is normal, but people are horrible. There's a reason SO felt the need to amend their Code of Conduct, and it wasn't just to score “wokeness points”.
