3 Games in a row with afk-trolls and i know they won't be punished but maybe my mates 4 flaming them

First Game: Brand whined that he had to use flash at our invade. We used ~3 Summ's. Enemy team had to use at least 6 Summ's. He still managed to give them FB mid. Then he said "one more time and i afk" He went back on lane, died again and went afk for the rest of the game. No one flamed him before that.

Second Game: Udyr died several times toplane Then goes trollmode, pushed bot alone the rest of the game (but extra slow so that enemies could defend tower). Refused to play in team. Farmed botlane even when enemy team kill our Inhib 5vs4. Sometimes he went afk for 5 minutes (maybe 15 minutes in total).

Third Game: We invaded and Thresh accidentally took the kill. Syndra raged and instantly pressed/wasted her two summoners after that because tilting over "KILL STEAL!!" Then she starts flaming Thresh, trashtalks all game, constantly pinging us and starts inting (2:9 stats)

All have been reported and i dont expect a SINGLE penalty for them. But i expect a penalty for me because i flamed them for their childish behavior! Things like "stfu and play you idiot! stop blaming/whining"

I dont have problems with flamers in this game! They can flame as much as they want, as long as they can PLAY! I am an adult, i dont care if someoine flames me in a game. But WHAT i care about is losing game after game because of afk-trolls!

And exactly THIS is the thing your algorithm doesn't punish! It only punishes flame but nothing else!
