Banned for scripting???

So I have played league since season 4. I got gold in season 5 and was climbing pretty fast until my world got all shook up and me and my wife had a wonderful baby girl. I took a long break and finally got some time to play the game again. I started playing again a few months back. I had recently taken a short break only to come back and see I was banned for scripting. This cant be right since I have never cheated a game in my life! The only thing I have on my entire pc that can be use to cheat is an automatic clicker which I use for adventure capitalist and wouldn't even serve a purpose in League. Please help me resolve this issue - Lazuhr
