Banned for no reason?

I just came on to try and sell some gold to some legit traders and I come to find that I am banned. I have never scammed a day in my life and it's weird because I don't sell or buy from normal players I only sell and buy from trusted sellers and buyers and I always go first, so I don't know how I could scam, which I never have done. So I'm really confused on why I am banned right now, just came on to try and find a buyer who wanted to trade ikov for rs3 gp and I found I was banned. Also I've had that account that was banned since the start of 2009 and never had a problem with anyone, don't you think if I wanted to scam which I don't I would make a new account and not use a 6 year old account? The account that was banned was H2kill, I'm using my brother account right now to write this for you to review.
