Guys
There is a way you can stop it
In your listing you state " Will not ship to unconfirmed address "
" Do not bid if you have less that 5 positive feedbacks"
" Will not ship to Nigeria or other non ebay approved country"
AND STICK TO THESE RULES OR YOU ARE OPEN TO BE STUNG.
Always check feedback, always buy from sellers who have great feedback, always strick up some email comms before bidding to assess the seller/buyer and NEVER NEVER buy using paypal unless you are covered by there protection, they will tell you when you come to bid and pay weather protected or not.
Ebay is a great community if you are careful and keep your eyes peeled as there are lots of scammers out there now yes, but you should and can spot them a mile off.
