I'm trying to use Bing's Content Removal page to remove an old domain from search results. The domain belongs to an old staging site and is no longer live, but got picked up by Bing somewhere along the way. When trying to remove the URL Bing returns:
We could not verify that the URL is no longer live on the web or outdated. Please check the URL for errors or try again later. Your request will not be submitted.
According their help page
If we are unable to determine either (for example, because we cannot connect to the server on which the page resides) you will not be able to submit a page removal or outdated cache removal request at this moment in time.
Bing won't be able to connect to the server because it's no longer there. I could go through the trouble of setting the domain up again from scratch and pointing it at a file that just returns a noindex header, but that seems a bit silly/overkill to get the page de-listed. Is there any other way to get Bing to de-list this? Why would they make it so difficult to de-list a URL for a domain that doesn't even resolve?
