I own a domain. In the past I haven't care about the Bing search on my homepage. Now I found some strange requests in my server logs from the Bing robot. I created an account for the Webmaster Tools to figure out what happens. But didn't find a clear answer. Formerly my homepage didn't return the correct answer 404 on invalid requests. The site was always returning code 200. It was a mistake in my PHP code. But I have fixed this bug on the last days.
The issue: The Bing robot tries to request some sites which where never defined in my sitemap.xml. Also in the past. But I can't find any information in the Webmaster Tools.
Is there a way to show the full index and delete this "unknown" URL's from the index? Or is it possible to remove (reset) all current data for my domain?
