Misinformation covers situations like defamation and many kinds of hate speech.

Not really:

• Misinformation: “false information that is spread, regardless of whether there is intent to mislead.”
• Disinformation: “deliberately misleading or biased information; manipulated narrative or facts; propaganda.”

The difference is between "I don't believe you, so you get banned" vs. "I think you're trying to mislead people, so you get banned".

Misinformation allows banning any information a mod believes to be "false", for whatever reason, no matter the proof.

(PS: if any mod doesn't agree with these definitions, they could remove this comment based on "misinformation")
