See, I rarely ever see anyone ever actually intentionally feed. Maube one out of every sixty or seventy games. I will see people who perform badly, and people will just shout "REPORT FOR FEEDING!!!"
And when I see those people, I feel more inclined to report the person asking for a report, rather than the player who performed badly. I understand everyone has off days and won't always perform well. I also understand not everyone has the same definiton for what is good and what is bad, so I will NEVER harrass someone for performing poorly.
I imagine how bad I'd feel if someone did that to me. And I see it so often, someone will go 1/8/1 or something along those lines and people beg for you to report them. I feel that as far as communities go, the LoL community is seen as horrible, and the way to change that is to show kindness, understanding, and don't tolerate intolerance.
This isn't to say that what the OP mentions never happens, because I've seen that too, where someone does intentionally feed, and you get the "lol who cares, not my problem scrub." But the rant is for both sides. Try to use fair judement, and most imporantly, don't be a dick (Not say the OP is either.)
