My league of Legend has been permanently suspended, without any reason.

If there wasn't a reason, you wouldn't be suspended.

Does this "no reason" happen to consider those games that you bought multiple of the same boots?

That's typical behavior for someone who is intentionally throwing the game.

Did you violate the Terms of Use? Did you share your account (which is a violation itself) with someone that may have? Have you received punishments in the past? What was the reason for your ban? Did you get a reform card with in the client and an email?

On a side note, Gotham is an amazing show.
