No matter what it is in life, when you get some fame or attention there will always be a large handful of people who will dislike you or whatever you do no matter what. Just the way people are. Its easy for people to get jealous when they see you find something like that then see how much $ its worth.
People react without knowing whats really happening. Youve tried to sell the item legitimately its not your fault people backed out.
Id just ignore everyone, and chose your own path on what to do next.
I would say if you decide to list on Ebay again make a LARGE disclaimer at the top of the auction. Ive sold some very high end items on Ebay and I always make sure before they read that only serious bidders can bid. Anyone else who wins and doesnt pay will be reported to Ebay as a non paying bidder. Show em you mean business. Otherwise a bunch of kids are going to bid to show their friends... or whatever reason they would bid and not pay.
