Where do we draw the line?

Ever played a game with a person who totally freaked out about stealing on cs or one kill?

Then that person plays in a way that is passive aggressive?

They might say something like, "Looks like you need the gold."

or, "Take my creeps, you can use the cs."

As a result of an honest mistake in an attempt to help a fellow teammate, you get punished by a passive aggressive player who doesn't group for fights, and play counter productive to winning.

Has this happened to you in a game?

How do we deal with these players who don't say anything wrong, but we know they are trying to lose, but it is not obvious, so they don't get seen on the Riot radar?

We always see blatant chat restrictions and perma bans for overt a hole stuff here on the forums, but what about those not so obvious people who have been skirting the limits of the rules, getting by and ruining so many more games?

What do we do about these guys? I think this is the worst of all the problems here, because they do this non-stop, and unchecked. They usually will do this to teach someone a lesson and cause someone else to tilt or flame people on the team, resulting in another player losing it and getting banned. This kind of manipulation is despicable and you are the people in my opinion that do not deserve to play the game, because of the ceaseless damage to do to the community.
