It is impossible to determine a scammer simply through a feedback score, be it high or low. Scammers always tip their hand, but that will not be evident to a seller until it happens. So it is not possible to determine which buyer might scam you ahead of time.
The time to examine one’s risk tolerance is always before listing an item. Especially not after the sale. Cancelling transactions can come with steep penalties, so i don’t recommend anyone attempt to manage their risk after a sale has transpired.
Say for example, a zero feedback buyer from Nigeria is the winner of your auction, a country known to breed scam artists. You are on the hook to ship regardless of who and where the winner resides.
And sending fragile items into an overseas two month rough transit is also risky. Some countries have subpar postal systems. Some have corrupt Customs agents. (To protect yourself, you can set up shipping exclusions in your Site Preferences to avoid countries with suspect systems.)
As a new seller, i tell loved ones just starting out on eBay to avoid listing expensive fragile items. Best to learn the ropes first. Selling on eBay is a rewarding, but demanding job. It takes time to learn everything necessary to be successful here.
Good luck to you, and best wishes for a profitable and smooth sailing experience.
