Dear anjul.vikku ,
Nigerians target high value Items.
If you sell high value Items and don't ship to other counties then the best is to block those Buyers.
Go to
Preferences under
My Account
Under Selling Preferences you have Buyer requirement.
Click
Show against Buyer requirement.
Click
Edit.
Under
Select requirements you have
Buyers in countries to which I don't ship
Just tick the box below this and anybody registered abroad would not be able to buy or bid your Items.
If you have problems with fraudsters registered with Indian address then for him you may tick the boxes under ....
Buyers who haven't gone through the SMS process
Since those fraudsters are not verified through SMS, they too won't be able to trouble you.
