*sigh* I explained this all very specifically in PM to you.
The rules of main chat are for that. The main chat. I, as a staff member, explained it in full detail to you. We generally do not get involved in PM's. I also explained there is an exception to that, when one user is an adult and the other is a teen. OR if its something illegal like cp. Your age also plays a big part of it. You're 40 years old (well into your adult years) arguing with a 56 year old. We don't give a **** about 2 adults trading insults in PM. We also don't have to write this down and send a rule list to you. It was explained as a courtesy to your questions.
You want to talk about laws? OK lets - How about the law of common sense? Weird you chose this to complain about when you have posted inappropriate pics in main, had inappropriate conversations with minors. Maybe the laws should look into you.
