I appealed to my 2 weeks banned account and it got unbanned...... 11 days later.
i wont even mention the word compensation. My account got unbanned after 3 requests to riot.support, and after 11 days had pass while i unfairly couldnt play any games. Yeah, 10 days ago i got 2 weeks ban on my account. Then i made a ticket to riot support saying it is undeserved and i wanted a review from a rioter. (sry for my englando) tl;dr : i got 2 weeks ban because of my inflammatory behavior in the chat, but it seemed totally undeserved. Then through a series of requests and discussions with many and different rioters in the RiotSupport, i got unbanned. Some Rioters at the start closed my tickets saying "case closed, your punishment is totally deserved", but later some others actually spent some time to read what i say to them and view my case and they finally unbanned me.
These are the chatlogs (they mean nothing, but im sure some would ask for them) : Game 1 : http://link.email.riotgames.com/YesConnect/HtmlMessagePreview?Ji4ptIIdVvyGJizHZtDMRTaZPGM0GvuiPqFK%2BldZGhk=.enc&msgVersion=web Game 2 : http://prnt.sc/ahuia0
The riot support marathon : In the 1st ticket, a rioter said he would forward my request to a player behavior specialist, and that player behavior specialist said my behavior and my chatlogs were totally deserved, he explained me why, and then he said he considered this case closed. This ticket last 6 days... Then i made a 2nd ticket, the 1st rioter said he would forward it again to a player behavior specialist, then the player behavior specialist added it to my previous ticket, and then that same rioter from the previous ticket replied again that my punishment was well deserved and he closed my requests saying my case is closed. Then i made a 3rd ticket, this time in my own language (greek) in order to get a different rioter. This ticket last 5 days total, with a 3 days gap in our conversation with riot w8ing for their final reply. At first a typical rioter said he would forward it to a player behavior specialist. Then the player behavior specialist (clearly the 1st one who actually read what i wrote them), said nothing at all except that he would forward my case to a technician specialist (or something like that). Then that last rioter posted some system details proof showing that the 1st game from my chatlogs was played before even my last punishment with 25 chat restricted games, and then he said he would also forward my request furthermore to another rioter. And finally, after i w8ed 3 more days for that other rioter, a Player Support Coordinator Specialist Rioter (the fuck xD), replied to me that he had lift my punishment because it was indeed found undeserved.
Conclusion : Yes you can get undeserved punished, either it is 10 chat restricted games either it is a permanent ban. No, making a single RiotSupport request may not 100% work, because as i personally witnessed some Rioters are biased beings failing to do their job. I thought Riot had the biggest salaries in the gaming industry. But rioters still dont give a fuck about others. They wont even spend 5 minutes to read what you write to them in the tickets. they just send out the same bot messages again and again. You have to be persistent, and repeatable. It may take you to type the same thing copy-pasted more than 3 times in the same request so they can pay attention and read it. They will most likely not read anything you say, read only your chatlogs and proceed telling you that that behavior is punishable because bla bla and bla, and then they may close your discussion too, just like it happened with me. But you gotta make another request, and another and another, untill an unbiased rioter who can do his job sits his ass down and finally spends 10 minutes to read what you write and deal with your case.
So yes, you can get punished based on only one game and based on false reports, exactly like it happened with my case. My punishment was based in a total of 5 games. In the 4 of them i had the exact same behavior as the 2nd chatlog. I received false reports in all of those 4 games. The system triggered and it wanted like crazy to find a reason to punish me because in his "eyes" its not possible to get reported so much from different players unless you are doing something wrong (in my case i was doing wrong not being a smurf, thus feeding and losing my team's games, while they were flaming me all the time. i am level 21, most others here are smurfs). And so it found a game from my past, the 1st chatlog game, to punish me. Even if riot themselves stated that false reports do not count and that you can not get punished based in only one game of yours. Even if you are the incarnation of evil and you say the worst things that can be said (like wishing cancer to everyone etc), even then you cannot get punished if you do it in only one game and in the rest of your games you are positive/neutral.
P.S.: i had made a thread here in forums a few days ago explaining totally everything about my case and providing all links and screenshots for proof. It is downvoted with -15 from the community. Because logic be "you got punished, you did something to deserve it" without posting any real counter-arguments. [slayer-pantheon-thumbs]
