We have a standing policy, included in the code of conduct not to discuss disciplinary actions.
Regarding players you may find in chat violating the code of conduct as you have outlined - First, I’m sorry you had to experience this. Making racist comments, spam, and excessive vulgarity are against the code of conduct. And while we certainly try to create the most welcoming environment we can in chat, we cannot guarantee all instances will be caught.
This is why we are both expanding our roster of community moderators, as well as introducing a report system with the coming chat system. Of course, you can always submit a screenshot with a support ticket if you feel something is going unaddressed, and we can ensure it is looked into and addressed appropriately.
As far as something being “civil”, it means to be courteous and polite, to follow conduct of good behavior. In other words, it’s a shorthand for following the code of conduct.
