Hi admins.
My account have been banned on dota2lounge with the reason that i am scammer.
My account had been hijacked by another user and i just took back my account at January 10th 2014.
And people reported me at the time somebody using my account and i didn't know what they did with my account.
I'm not scammer.

Here is the letter that steam-supporter sent me.

i am sorry, it's my first time appealing.
