Some of the steps we do to avoid the inevitable scammers (i.e. multiple registrations/user names by one person)?
We are currently working on an Id Verification system which work with a paypal and google checkout backend.
A seller has to become verified by sending TropicalFishAuction.com a $5.00 paypal payment. If the seller is a verified paypal or Google Checkout member, they will receive an icon next to their username. The $5.00 payment will be credited to their account balance and can be used for auction enhancements. While this is not foolproof nor gaurantee a sellers reputation or business practices, at least the buyer will know that the sellers bank information and address have been confirmed.
Protection for sellers:
A seller can post requirements in their auctions for potential buyers such as:
1. Must Bidders must be a verified paypal or Google Checkout member.
2. Only accept Money orders or paypal. or Google Checkout.
Another issue we are addressing is multiple registrations with different usernames. This is usually done for the purposes of posting positive feedback on themselves, raising bids or to hide a bad reputation. We do log all IP addresses of new members and will terminate any account caught using deceptive practices. There is a "Report Abuse" button in the member control panel which can be used to report any suspicious activity, failure to pay, failure to ship, etc...
Again, these are not all foolproof remedies but should help to protect buyers and sellers.
Unfortunately, there will always be some that try to scam the system, and these are issues that even the largest auction sites face, but we will do everything in our power to help protect our members and resolve any issues that may arise.
So far there where NO scams yet on our auction system
