What. Im not sure if I have seen anyone be more wrong on anything ever.
intentional feeding means you put yourself continuously in a position where you die and do not change your play style.
Nope. That is just plainly wrong. Intentional feeding is when you *intentionally feed. Not a hard concept. Bad players don't change play-styles. It might seem obvious to you and me that you should play safer when behind, but there is definently some who don't see it that way. You can't have an opinion on what intentional feeding is. It's not something to discuss. You can discuss IF a player is inting but not what inting is. If we go by your definition you would be an inter aswell. 3/10/2 teemo game. You're definently inting right? /s
If you are far behind and still charge or still fight, this is feeding.
Correct. What would make it inting is if they did it because they KNEW they were going to lose. Bad players don't have great risk assessment. I describe this because:
Having a bad day happens. Giving up so many kills and not starting to play defensive is an intentional choice. And therefore it is intentional feeding.
You state it as being intentional.
when I am so bad that i continuously attack people who are 4 lvls higher or go into 1v2 situations, this is feeding.
This is feeding yes. You do this because you are bad, not because you hope to lose.
And I think it is a huge problem that it is most often not punished, bc this actually ruins and loses the game for everyone.
Bye man! You should just quit league now! You're contributing to this problem aren't you? With that teemo game. (The reason I keep picking on this one game is because I couldn't bother to find any others.) As you say, it's a huuuge problem. That rarely gets punished. I can tell you this with 100% guarantee: It's never going to be. Intentional feeding is punished. (Not your factually wrong definition of intentional), feeding because of being bad will never be punished.
Not feeding isn't hard, if you have a brain and listen sometimes.
I actually went through your match history again. Here you go, you apparently have no brain:

There are probably more.
Now i'm not saying you're terrible at the game, or that you should be banned. I'm just pointing out your hypocrisy.
