most toxic thing witnessed

what was the modt toxic thing a league player has ever done, which you witnessed live

I witnessed a player using all chat to rat out his whole team and told them where they were and literally everything

In a ranked game 2 days ago I was playing ezreal and my supp was thresh. He "tried" to counter gank a k6 and he died. He said "f*ing team" and just stay in our jungle all game. We won the game after 53 minutes. He was lvl 2 and put in all chat, gg ez game, carried by me. It was a x9 report for him. Hope that his account will be banned for that thing.
The other thing is just a normal, people verbal abusing all day. I play in LAS so nothing strange in that

i called a polish the n word and called poland a jew infested shithole because he inted and flamed all game. never playing EUNE again.

yes i know i know know know know now know know know now know know know

i used to spam toxic things in all chat, feed and intentionally throw games and troll teammates to make them ragequit until i got perm banned in 2012

The most toxic things I've seen in League is when Riot bans my accounts and shows me all my chat logs haha
