AFK

Are we allowed to afk all game and not get punished? literally every other game a person afks and it's much worse than toxic people. At least toxic people continue to play versus afk ppl making it an auto 4v5.... Why are afkers never punished or barely ever punished... It happens way too often that I feel like afkers aren't treated as severely as they should be. Please riot make the afk punishment harsher...... It happens much too frequently to not be punished.
