Trade with caution because of bug

A couple weeks ago there has been a misunderstanding wich got me banned.
My friend Making Rice recommended me to start selling GFX on Sythe, so while i was in a skype call with him i decide to sign up wich didn't work out.
No matter how long my username was it said i had to put in atleast 6 tokens.
So i asked him if he could sign up for me since i really do trust him.

So i posted my advertisement thread and he obviously vouched for me since we work together, Than we both got banned because his IP is registered on the same IP as mine and it looked like he was vouching for himself. Now i have a trade with caution mark next to my name wich really sucks.

Hope someone can help me out, Ty in advance

How are both your accounts registered from the same IP?

 

He registered for me , so his IP got linked to my account..
