Ebay has made my life so much easier. At first I had some doubts like most of us, but very soon all that have changed. I become regular buyer on eBay. Sometimes I was the seller as well. I never experienced any kind of problems. That is why I was shocked when they inform me that my account was suspended. Why would they do that?
You must have broken some of their rules. They have many rules, and you really should be very careful. If you were involved in shill bidding, the punishment for it is suspension of your account. On the other hand there is always a chance that they have made a mistake. The best thing you should do is to contact them and ask for an explanation.
