This should help
To add buyer requirements to all of your listings:
Go to the Account tab in My eBay and select Site preferences.
Under Selling preferences, click Show next to Buyer requirements and then click Edit.
On the Buyer Requirements page, select your buyer requirements. For example, you might not want to do business with buyers who:
Don't have a PayPal account
Have unpaid items recorded on their account
Are registered in countries to which you don't post
Have reportedly breached eBay policies
Have a negative Feedback score
Are currently winning or have bought a large number of your items in the last 10 days
If you want to use these settings for all your listings, tick the box next to Apply above settings to current and future listings.
If you want to prevent blocked buyers from sending you questions about your listings, make sure that the box next to Do not allow blocked buyers to contact me is ticked.
Click Submit to save your requirements.
