Hmm. Reporting someone for good/ bad sportsmanship is entirely different than whether or not you enjoyed the game or think that you played well.
I think most people understand the difference or learn to understand the difference.
I have seen people complaining here about poor sportsmanship restrictions placed on their accounts. They got the message.

At the end of each game ... should be a like a star system five stars means you enjoyed the game one star you don't enjoy the game that would be better than sportsmanship rubbish which obviously doesn't work
