Banned for AUTH CODES???

Hello i was recently banned by skele master for authcode scamming.

1. I didnt scam
2. Authcodes arent aloud on sythe so thats just bs
3. I blocked the kid and you can see in his msn because he did not give me a working auth code.

This is a unrightful ban. Also it stated i was more likely to scam again in the kids thread i had just finished 2 trades positively prior to this. I am lost how i can get banned for something i didnt do and something not aloud..
