Recently I was banned on tf2outpost for this reason(http://www.steamrep.com/index.php?id=76561198010875719).
I want to say that I never had the intention to scamm someone.
At that time I bought from j_chan7979 CSS for Bootle The Time.
at the time (2 Jan) Bootle Time Wass around 3 keys on Team Fortess 2, hee was a new items.
I just wanted to make a small profit, not to scamm.
Honestly at that time did not know what Gues past, a friend explained to me what it means.
I apologize to the person Not Sure.
