I've been playing for 6 or 7 seasons now and this one seems to be the worst in cases of bots and toxicity. Riot changed to am automated banning system and it simply doesn't work. Trolls, smurfs, and bots will ruin your game if you wish to play seriously. In addition the matchmaking system is flawed at best. I recently uninstalled the game and hope that riot will fix these issues in the coming season because I do love the competitive nature of the game and skill expression. However, toxic players have ruined this game for me in the near future. Unfortunately it appears riot doesn't want to ban these players out because it will hurt their revenue.
