Third Party Program Spammers.
I just had a player using what I think is an illegal third party application, they basically started the game all looked normal but then intentionally ran into my lane, and got the enemy fed throwing off the entire game, then started spamming buff timers along with mkjogo.com in game chat, which was an automated system typing information into chat.

No software should interfere with the League of Legends player experience between when you press Play and the end of game screen.
It really upset me because I feel software such as this provides an unfair advantage and is not part of the game client itself so it should therefore be illegal.
Also Riot can we get an option and get Riot to manually review toxic games I mean I have had junglers Griefing flat out throwing my lane in multiple games, even when asked to please stop coming mid, they come into whatever lane im in and get the enemy fed even when I am winning the lane and get the enemy ahead, this type of toxic behavior, then not listening and them keep arguing in chat needs to stop. This behavior was followed by other players being racist in the same game and leaving the game.
Can Riot please start to take action against this I am tired of the toxicity from players, and racists in games like its annoying having to likely end up with restrictions because players are going to be toxic spam report and are the ones trolling the game.
