So according to riot support Offensive Language, Verbal abuse, and Negative attitude are one.
Was given a chat restriction for Offensive language, which I thought was funny as I never personally attacked anyone, apparently it was my negative attitude. When asked why I wasn't being penalized for my negative attitude this was the official response.
Edit: Agent explains that in essence, though Verbal abuse, Offensive Language, and Negative attitude are seperate subcategories when filing a report, they all have the same criteria and punishment, which will be listed under "offensive language" on the in game client.
