Well, I completely agree in that part where you say they shouldn't be said, -at all-. but it would be a bit more of an easy task for GMs and/or moderators if they implemented a language filter for World Chat. It would be useful towards GMs since they can't stay on 24/7 and moderate, to my knowledge. Yes, I understand scripting something like this might be a small challenge, but it's just my opinion. If they were ever to implement this type of thing, it would be logical for players to be able to send screenshots in of those using strong language towards others, or in World Chat.
