Will i get banned?

Yeah i never been toxic or reported for toxicity or anything and i was looking online and don't wanna lose my account:( just wondering though. thank you!

Sounds like you need to take a step back and reevaluate your reasons for playing the game. If "for fun" isn't in there, take a break until it returns. You aren't a pro and the likeliness of becoming one is slim to none, therefore winning does not determine your pay, influence, etc. . Although you should have a competitive attitude and fight to win, winning should be low on the list for reasons you want to play the game.

It might help you to set your expectations more realistically, as the reason you got upset was probably that your expectations were violated.

try to keep in mind that league is an objective based game, not a killing spree game. Killing enemies can help facilitate the taking of objective advantages, and dying can cost you and your team advantages, but simply dying or getting kills is not inherently good or bad with regards to the game. What is good or bad is only what is done after those kills/deaths occur.

This is why teams make comebacks all the time when their opponents sweep them but then waste their advantage by not taking objectives and simply trying to farm more gold so that they can kill the enemies harder when they respawn.

Edit: This can apply to other players too. If you're upset that another player is trolling or flaming or feeding, remember that they are probably just upset over something and don't actually mean whatever insult they just slung your way. I know this is easier said than done, but it's still true.

Just wait for post-game where the chatlog doesn't show up.... It's where I leave all my racist rants towards bad players.

I'm sorry to burst your bubble, but Riot can see your post-game. A lot of people have gotten fucked by Riot Tantrum because they thought they were in the clear for saying bad things in post-game. Just wait until someone files a support ticket with screenshots of your post-game racism and see where that goes.
