I got put in low priority queue for 5 games for being afk for one minute

basically here's what happened, the game was 1-6 and they had a fed broken ass jungle fizz at 5 minutes so our mid went afk and then basically our whole team agreed to and let them push mid. LITERALLY ALL FIVE of my teammates went afk and sold items etc just minutes into the game and i went afk too although i was moving around at fountain repeatedly. i cant believe how severely i was punished for such a small thing as that when everyone in the game was cool with it and i didnt even leave the game.
