Toxicitysolved.game LOADING 0...........................50%........The future
Riot bans ~1/500 or less of its community ,and they just make a new account afterwards.
If you worry about report system, you must be new.
If only riot banned everyone who deserved it, we would have 30min queues, so i dont know whats worse.
Honor system wasnt a solution as well, it was a bandage. Nowadays people spam-report honor lvl 3 players, just to make them snap.(Since Honor is shown like a bullseye)
Cant cure toxicity.
Good thing ,is when you even blanco report someone, high chances are that you will not be seeing that person soon,since matchmaking avoids bringing you together again, so many implications, but than again, trust me ,you will get other ,toxic players, in no time.
And there it is, you are stuck in hamsters day. 
So, straight out, it does not matter what they do, like ,at all.
The most toxic players play on dummy accounts, and not worry much about skins, you might know them as john3213, or more original, millenials mommasboy98, they can even combine toxicity with naming, inception method, if*kyomama01
You need to seriously try hard to be banned, and i mean, get 5+ games in a row by being worse you can be, than do 5 more after the warning, and than MAYBE, you might get banned.
But since its not an IP ban, you just create a new account, and rince-repeat.
It has existed for years now, years.
Everyone finds their own ways to cope with toxicity, some do allmute ,some mutefull, some just dont get triggered, some get triggered, and troll others in return, some play 4/5, 5/5 premade games and than write on these same boards that League of Legends has no toxicity
,and than all the rest of us ,enjoy the game becouse its fun, and dont give craps ass about some crybaby who blames others, or trolls, or bad game, becouse we are mature enough to know where it leads.
Have fun
these guys, sure do :)
