We understand your concern regarding adding additional information to your Proxibid profile. To help keep our Platform secure, sellers have the ability to set special requirements for event participants. For some events, a seller may choose to institute a higher level of security for buyer registration. Proxibid will store the information in our system for future verification purposes. If you do not wish to enter the additional information, you may contact the seller for manual approval.
