Proxibid's only concern is serving the auction companies, not the bidder. I had a false complaint filed by an auction company employee I had personal conflict with. As a result Proxibid has blocked me from all bidding through the site. Proxibid's employees, whom I chatted with repeatedly, know this is incredibly unethical and they often apologize for the problem. They repeatedly promise to have someone call me to correct it, however, no one ever does. This is a shady company. I still bid in the auctions but I go to the site, never using Proxibid.
