Abuse of one's position of power — mostly, but not strictly, one's journalistic platform or social media following — to attack, intimidate, shame, libel a person or group. May also used for criticism that is otherwise legitimate, but appears to be exaggerated or escalated for the intents stated above.
Also used when a journalist directly and willingly engages in doxing or harassment — or encourages others to commit them.
What constitutes "harassment" is, to an extent, arbitrary, and thus DeepFreeze doesn't list acts of perceived racial or sexual intolerance unless they appear to be part of an act of intimidation. Threats of violence, though, are always listed.
