0.05 is quite good price for a full member account.
Yes 0.05 btc is a goo price but I can't just accept the bid from a newbie account. If the guy can't provide a proof ten his bid is not valid. It is necessary to prevent peoplw from messing in auctions in biddin high then if they win they will not payso I wan to make sure he has the coins to pay. Also it is to prevent newbs accou t from raising the bid even if their bid is not serious, it will not be fair for those who have serious bid.
