I agree that the report system is absolute garbage. That being said, I wouldn't quit LoL because it is a fun game. Take the vow of silence and choose to say only "gl hf" at the start of the game and "gg" at the end of the game. For the remainder of the match, do the following:
These 2 steps are NECESSARY for not getting perma banned.
- DO NOT TYPE
- DO NOT COMMUNICATE WITH YOUR TEAM (pinging is acceptable) because people will assume u are being a sarcastic tilting fuckwad (i.e. saying please play safe = get comments of fuck u fuck u fuck u reported etc.). Further on this point, not communicating with your team is NO LONGER A REPORTABLE OFFENSE.
This is the ONLY way to ensure you never get perma banned after receiving a 2 week suspension.
I feel for u bro, I got an acct perma'd for the same reason (used the same exact words u did, stupid/idiot). I wasn't racist/homophobic; I defended myself against those things and let my emotions type those words (the ones mentioned above, I am still justified imo for my comments to those players) but 4 man report is OP bro and it needs a nerf.
Finally the last thing you need to do is:
This third and final step is COMPLIMENTARY to not getting perma banned.
- Never solo que. Riot hates solo que players and this is why Dynamic Que was introduced. If u are a trolling 4 man, riot LOVES u. I have known and seen many players that LOVE to try to TILT and harass players into BAITING them into being reported. If u have more teammates on ur team, it is less likely that you will be reported in any given game. (also if u are solo and u report ur ENTIRE team, riot may flag you for excessive reports that are now seen as inaccurate and this is a ban-able offense as well; let that sink in for a second).
^^ btw, ya that works, go try it.
Finally, in all seriousness, riot wants this game to be more team oriented and they are willing to BAN solo que players to accomplish that goal #LEAGUE=ILLUMINATI
Final note: The reason you were permabanned was probably ur toxic behaviour (i'm going to assume it was a little more severe since u did not post chat logs; I understand that you didn't because riot doesn't normally have the balls to send the chat logs to u in the first place and then tell people OMG SAVAGE 
look at riot throw down the ban hammer guys what a POS toxic summoner).
Reason u were banned, you didn't follow steps 1 and 2. Also you can solve those problems by becoming a 4-5 man premade and play the statistics game. The less reports, the less likely you will be banned.
That is all, this post will likely be removed but I hope it helps u bro. Maybe now u can sleep at night (jk ur prob leveling another smurf to level 30 as u read this)
Upvoted btw.
EDIT: actually I read ur chat logs and u were quite toxic; I was surprised that riot actually gave u the chat logs. Switched my decision to downvote.
This comment seemed a bit racist "Jakeypoo1324: english,please..."
And this one makes u look real bad "Jakeypoo1324: kill yourself", Why hef to be mad, is only game.
You don't have to type to communicate with players that cannot speak english. Pinging is a universal language in League.
My advice on not getting banned still stands and u should take it as this game is still quite good.
Please bring back the tribunal, that thing was wayyyy more accurate in determining toxic behaviour
EDIT EDIT EDIT: I take back any defending of the original poster; I didn't read everything before posting this here. It turns out that he was a racist and RIOT is definitely JUSTIFIED in banning this toxic player.
