New abusive buyer protections and reporting feature update
We're implementing stronger measures against buyers who don't follow eBay's abusive buyer policy. We're introducing new measures to proactively find abusive buyers, prevent them from filing return requests, and in some cases suspend them. When we find that a buyer violated the policy, we will remove any feedback and defects, including opened cases in service metrics.
We've also made it easier for you to report buyers who violate eBay policies. Now when you report a buyer, you can more clearly describe what the buyer is doing to help us investigate potential policy violations and take actions to protect you.
