Once a few years ago, I got banned from my league of legends account for cheating. I was playing Overwatch when it came out so I did not even touch my League account for almost 4 months at that time. I have seen that someone actually broke into my account and was playing on it. I could see clear as day as I NEVER play Yasuo... I am a support /caster kind of person, I hate close combat champs.

I wrote a ticket to them to appeal. I explained to them to look at my play statistics and look at how many times before that I have played Yasuo... literal never...

They got back to me and said that they seen 3rd party tool usage and I cannot prove that it was not me, so they cannot lift this ban. I said to them, just look at the games played, I barely ever played ranked or Yasuo... Then, they said no, then, I let it go. I was playing Overwatch mostly anyways, so I just thought "whatever".

Then, almost a year later, I receive a notification in my mail from Riot asking "did you change your password?" to that account that was broken in once. I immediately wrote to Riot again, that look this is 100% the guy that was stealing my account, I can prove it is my account, and I can prove its not me cause the request came from a different country...

Low and behold, they actually apologized and gave me back the account... too bad I am not playing that game anymore.

There is no moral to the story... when GMs in any game decide something, they decide something and its done until you have further proof. I did not just got my account hacked they banned it instead of helping me getting it back...I am not saying SE is same as Riot, but people are people. It will highly depend on the person that reads your case on what will be the outcome.
