Why Ban made 20 mins game league of legends

I played a game and when I finished I played another game but when I chose the hero I played I closed the game on my own and I got a message telling me that the game needs to be fixed. When I finished the repair I finished about an hour or more and when I opened my account, I have a ban 20 mins so why did this happen? I do not have any interest in this subject and why did the game company do this? Well, if and if someone in my family is exposed to an accident or anything that compels me to get out of the game and care about him and why I care about the game about my family and my life Realism I'm just a game not the world I live in Several of my ideas rather than ban 20 mins, for example, for the one who can fall down from the game only gets xp and ip for 5 matches or be 5 or ban 10 minutes and it is not 20 or could be the one match ban 30 minutes There are a lot of other options much better than this and please the game company to give attention to this subject there are a lot of players left the game because of this ban silly and incomprehensible The game can do a global vote to remove the ban old one new work and thank you for listening And to throw.
