EBay favorite sellers?

[Richard]

My wife and I try to sell our daughters pageant dresses but continuously have members with little or no feedback win the auction and never pay and not return emails. We are beginning to think someone is doing it on purpose because it's happened four or five times now. Is there any way to find out who has us as a favorite seller or delete us from their list without knowing who they are? It's frustrating because it's a waste of time and money. Any advice or knowledge would be appreciated.
