Greening is the act of disrupting Cog battles with the intention of making other Toons lose laff, which can cause them to go sad. An act of greening should not be mistaken for players that are learning to play Toontown Rewritten and players that have Toons with low laff and/or low level gags.
Greening is strictly prohibited on Toontown Rewritten and violates their Terms of Service. Such behavior should always be reported by using the in-game report system or contacting the Toontown Rewritten Team's Support department by sending an email to support@toontownrewritten.com. When sending an email, Toontown Rewritten instructs to provide username, Toon name, time and date of incident by timezone, misbehaving Toon's name, misbehaving Toon's ID if possible, description of misbehaving Toon, and details of the incident.[1]
