Private feedback is essentially for plonkers..

If say you'd bought something you didn't want others to see.. Or you were going to be selling highvalue stuff with a new account..
As an ebay employee I wouldn't stick anything on this board unless I thought it to be kosher..By all means though - if you come across a listing which you think could be a bit dodgy..use the ask seller a question to suss them out..
Oh and never never use bidpay, western union- or cash as payment..Big Big no no!
