Here is what I believe:
1. The Scum 'R Us section promotes verbal abuse, how so?
John says the following after being killed by Sam "Screw you *insert foul word here*
Then Sam reports John for foul language. John now wants revenge ( like most people) thus provokes Sam and gets Sam to say something foul. Thus who won? Noone did.
2. I don't believe provoking then screenshotting is right.
Martha gets killed in PvP by Daniel, Daniel says "Thats right *insert foul word*", then Martha replies with "Oh yea you are a *insert foul word*", all Daniel has to do is screenshoot what Martha said and report it. I believe in this situation both should be punished equally, this will help keep the people with foul language at bay as well as make people realize its MUCH better to stay silent and screenshot it than to curse back.
