Ridiculous perma bans.

Hi. I started playing League of Legends in 2013, but stopped for two years and started playing again in summer of 2015. I play a lot of CSGO, but sometimes play LoL for fun in downtime. I was never any good, but had lots of fun and an overall positive experience. However, about a month ago, my main account, username gigabiter25 and summoner name embee, was permanently banned for toxicity. Now, I do love talking trash, and the ban was probably somewhat justified. However, since the game is free, I made another account. Now, it has been perma-banned too. But this ban is pretty ridiculous. The chat log was nothing out of the ordinary, but near the end of the game, the enemy Jax started talking trash. I was playing bard, and after every message the enemy Jax sent, I would just say "ezzzzzzzzzzzzzzzzzzzz" with nothing else, except for at the end "ggwp". Bam, perma banned. I think this is pretty ridiculous, and I want to say that League of Legends is T for Teen, and they should be able to handle a bit of trash talk now and again. I have already made another account, and will continue to play the game because it is fun, but i think that Riot Lyte needs to calm down and realize that this game is not for little children who cant handle trash talk. It also says that i am among 0.0006 percent of players that have been banned, but i dont think thats true.
