How to Block a Buyer on eBay

Reasons to consider blocking a buyer on eBay
The act of blocking a buyer is distinct from blocking a contact on WhatsApp or Facebook. In addition to being able to view your listings, the buyer will also be able to communicate with you.
The practise of blocking purchasers on eBay should not be commonplace. Occasionally, though, you may have a valid reason to restrict someone from bidding or purchasing your things, especially if you have had a poor encounter with a certain customer in the past.
Among the valid justifications for excluding a customer are:
Purchases not paid for
Withdrawing offers
encounters that are harmful or abusive
Fraudulent activities
They are a competition, and you do not want them to be able to buy your stuff.
Once you block a bidder on eBay, their access to all of your listings will be denied. For this reason, eBay cautions sellers to utilise this function with caution.
