Being reported has always been par for the course. I don't recall the last time I had someone try in get in a whisper war with me, but there was a while where I constantly had my toons set as /dnd It's called multiboxing. I'm not cheating, I'm not selling anything blah blah blah. If you have a real question, ask after the beep. or something like that. Most people who are going to report me just do it quietly.

They're looking to get you to into an argument so they can report you for harassment or vulgarity, which they know you can be actioned for a lot easier.
