We have an issue though!

He created a non-steam trading website so he created his own trading server!
Therefore i cannot post my trade history!

Here is my improved report (thanks to Nero) Only a few days ago, a friend created a fake bot trading warehouse like Tf2WH, i traded him my items for *credits* and after i traded him he removed and blocked me from his list. This scammer also created his own trading server so my inventory history doesn't display his scam on forums like these.

Here is the website link: http://www DOT tf2storagebank.webs.com
He possibly removed it so no-one can find he's a scammer!

Little does he know that i can easily report him!

how can i break such a crime?

I Apologise mattie! , Im trying to spread the news about this issue and have only posted this issue twice! Can u please put this report into further admiration?
