This is clearly an assumption, just another thread about staff not doing their jobs when we all are clearly doing whatever we can to get rid of the exact types you speak of. If you see it, report it, and then let the staff handle the rest. If you think you can do better, sign up for modding, and maybe then you'll truly understand how it all works.
Keep in mind that chat sites anywhere on the internet are opened to the public, which means all kinds of people from around the world can come into the room at any given moment. No matter how many bad apples we kick, there will always be ten more of the same type who will come in the room to cause chaos. Send the reports and screenshots to the staff, and be done with it. Mini-modding is highly discouraged.
