Unlikely as ebay would detect a seller bidding on their own items.
It is a silly member who either wants to hide their feedback, there might be something in it they do not want anyone to see, or they think that as a private member they should have Private Bidding.
As I say silly, as all bids are anonymous and have been for many years, just showing as a***b for example.
I rarely have any private bids and if I did have a winning bidder who was a private bidder i would not bother leaving feedback as no one can see it so what is the point.
If you feel uncomfortable with it, retract your bid.
