Reported !!
I really believe this is becoming an issue. I know I'm get tired of reading this statement/threat in a lot of games and now it seems to be creeping into the boards. Normally, I wouldn't think twice about it being said as far as reporting goes, but lately I have been thinking about it different.
When you say "Report" for whichever reason all it does is escalate the situation. If it isn't making the problem worse then you are using it to bully others into not saying anything, simply because you don't agree with them.
And the worse use of it in-game is 'report x person for feeding' / Add whatever insult here. This never helps and it is getting to old to even claim to be funny. Also, I can't think of a legit reason to say it in all chat..
