I am seriously upset about being banned SO MUCH from League.
The last time I was banned I left only 2 GAMES total and I was banned. This time I AFKd in ONE GAME and I got instantly banned.
This is absolutely not fair. Riot needs to seriously increase the amount of games you game leave/AFK in because I bought 34K RP recently and I have probably bought nearly 60K RP total. It is seriously annoying that I get banned so much even though I spent so much money and I always try my hardest in games. And the cases where I do leave is because I have a serious medical condition which sometimes can stop me from playing because of too much pain. It's really not fair to me and I think Riot should increase the amount of times you leave by how much RP you buy and etc. because nobody has unlimited money to "troll" (leave/AFK just to annoy people for fun) people, which I am assuming is the reason to punish people for leaving games. And now I made a new account and I have bought 5800RP on this one and it got banned for leaving 2 games... this is ridiculous to me... if Call of Duty banned people for leaving games like Riot does then every single person on earth would be permanently banned.
You're getting banned by the LeaverBuster system. I really encourage you to check out our FAQ on the subject, because it will give you advice on how to avoid bans in the future.
You can find it here:
The TL;DR: You're getting banned after 1 leave because you've lost your "grace period". All players are given a grace period of leaves because sometimes Real Life happens. That would be something which prevents us from finishing a game: Network Disconnect, sudden emergency etc etc.
So if you're forced to leave one or two games, you don't have to worry about getting banned. However, if you leave too many you'll be bumped up to the next "level" of leaver buster. Now, whenever you leave a game you will get a ban, and be bumped up to an additional level. Each level will result in a longer ban.
This problem is fixable though. As you play games and you do not leave, then your Leaver Level will decay.
Eventually it will return to zero and your grace period will be returned.
