I have had a ton of problems fending off Nigerian scammers on my eBay auction for my laptop computer. I have listed the system THREE times on eBay now. The first auction didn't meet my reserve (but I got four emails from Nigerians trying to scam me), the second was bought using Buy It Now by a Nigeria within one hour of listing (though it specifically said only in the US) and I had to work with eBay to get my money for listing refunded, etc. (the person was already under investigation by eBay and was no longer a registered user). Today, I relisted my computer and blocked African bidders along with anyone who had negative feedback of -1 or more. So, a US based Nigerian used Buy It Now and wants it shipped to guess where. It has been so FRUSTATING! I want to sell my computer, but is there a way to keep these scammers out??? It's a huge pain in the neck to keep relisting, contacting eBay, etc. Thanks!
