If you're a moderator, you have to be responsible. It's like when you see a teacher out of school and you do something disrespectful in front of them. The next day at school, and they see you, they can't say anything because that happened outside of school, which is out of their jurisdiction. You are the teacher and shadow rat is the student. If he did something that doesn't have anything to do with the stream, then why does it carry over to this stream?
