You shouldnt recieve negattive attitude msg when you get reported.
I know why is there. But it pisses me off that some people report you for nothing, and then you get that msg, it's like a slap in the face. When I get reported and I actually know that I didnt something bad i just leave league for few min and cool of, but when I get reported in games where I bearly spoke, or was more playful than anything and then at the end of game that msg pops up it pisses me the fuck up and makes me want to give them a reason to report me.
