Don't let a few bad apples spoil the bunch! Sure there are some fraudulent or down right rude sellers, but that's ANY site you go on!
With their policy, it's easy to win back credits if they were lost because of seller not following through. Likewise if you have a problem with a winner, they hear your side of the story. The Moderators and Administrators are very knowledgeable of the policies and their customer service is GREAT! There are people on here complaining about suspeneded accounts and credits being revoked---it's simple READ THE RULES and FOLLOW THEM.
IF YOU HAVE QUESTIONS CONTACT CUSTOMER SUPPORT. They are super fast and helpful when you need them! If you would just utilize them you would not have suspended accounts.
Also, people need to realize that with the amount of auctions to staff ratio, there are some that slip through the cracks that shouldn't that happens. Read the rules, play nice, make friends, ask questions when you need to, and if you want to be negative don't blame a company for someone's elses deeds!
