This is my main account, it always will be and always has been. I've been toxic on this account for many years, even when I was banned I was toxic and thinking of ways to make smurfs and ruin the community. The banning system is unfair, but I admit sometimes I did go overboard and it wasn't justified. This account has been hit by every single punishment Riot can give even one perma-ban, yet it is still here, why? Well, there was one thing that removed my actively toxic behavior and that was an un-ban. When I was banned I was crushed, because of two things: time sunk into the game and my friends. For some reason when Riot bans you, it is no longer an option to even see your friends list or message them. I also got the elusive Angler Jax skin from a hextech chest a week earlier, which I paraded over my brother's head, and it was the only skin in the game I actually NEEDED to have.
I realized how valuable my account really was and it wasn't something to lose because I didn't want to follow the rules no matter how dumb they are. I would have went down the road of creating more accounts to ruin the game if it was not for one thing, an act of mercy. The last thing I did to recover my account was talk to Riot, I thought it was impossible, you always hear Rito saying "once your account is banned, it is gone forever". I'm going to tell you now that it is a straight up lie. I went to the dreaded page of community service and simply talked to a Rioter, we leveled, he did not want me toxic under ANY circumstance, and restored my account. I really didn't care for being overtly toxic, I learned to just drop things and let it go. Although the best way for me to stop being toxic was passive aggressiveness, non-direct forms of being toxic, or yelling at my screen.
In the end sometimes you can't avoid being toxic, it is complete human nature to get mad when you are losing a competitive game. The only thing that is in your control is if the things you say will get your account banned, keep the message the same but try to find a way that the system cannot detect it. If Riot wants to make their system unfair and abuse-able by those who report people, it makes sense that people who don't want to get banned would abuse the fact that indirect toxicity cannot be identified.
