BidFun
Naxopresence UK Ltd Requires purchase of 'credits' to bid, then repeatedly delay auctions beyond the expiration time listed to eat up your bid credits & you've just paid $50 for the chance to bid

One must purchase 'credits' to bid on a particular item. Every time someone bids (a shill) the auction is delayed (this happens several times, even after the auction has 'ended'), and you are forced to either bid again or let it go if the cost gets too high. You think you may try for another item a little later, however, they've taken all your credits and you're left out in the cold. Attempts to contact them go ignored so hopefully PayPal will be of assistance. DO NOT FALL FOR THIS SCAM!!! I did an internet search prior to participating but found nothing so that's why I'm reporting them here.
