People are very report heavy in this game, so most people only use guild chats (free company) and linkshell chats. If those people had anything negative to say to you, they were keeping it to those chats probably. Shout chat would probably be used more, but this game is full of tattlers tbh. You can be warned for instance just by simply swearing, it doesn't have to be towards anyone. Which is silly since we have a chat filter, but meh.
