Being "on tilt" is not an excuse to be a dick to your team
If you are having a bad day, bad game, bad series of games, or whatever, it is not an excuse to be a toxic player. For example: If you keep trying to 1v5 the enemy team and dying, then say in chat "lets just ff. i want to lose. i'm done, honestly," then I have good news for you: You will soon be done when your account gets banned.
