Their system is automated. If you were punished, you should have been provided with chat logs when you tried to log in to show the behavior you were punished for. It's not actual people looking at it. When someone reports you (all it takes is one report to get the system to look at the game... extra reports don't do anything), the system goes through the chat log. If you say things the system recognizes as toxic, negative, offensive or the like, it automatically punishes you. That's just how it works.
Long story short: If you are considering typing in chat to say anything that isn't positive, just don't. Then you won't be punished. Because the automated system won't be able to find anything.
