why would you trade a banned user who's scammed hundreds and hundreds of dollars? at the very least you should have asked for a confirmation pm and made sure he's not been banned on sythe for the last week... but anyway, your report is incomplete. read the stickies about how you have to report people for action to be taken. if you do that i can add this to his ban reason/he'll have to repay you if he ever comes back to sythe.
also there's the announcement at the top of every forum on sythe telling you not to trade king neuro... :/
