Ban Request my bad

So my trade for my vintage shortstop was updated as you can see - http://www.tf2outpost.com/trade/21915677#latest

I hid is offers but then the person decided it would be funny to add me.

Then starts to troll me on steam. I don't enjoy annoying trollers like most of us.

Thank you for your time and I hope a suspension can be handed out or something done about this! =)
