Had a client who failed to make payment on web development (photo gallery.) Eventually my action was to remove the pages & images with 410 Gone.
I submitted the changes to the big 3 SEs. Google & Yandex quickly removed the pages & photos. Bing took about a 10 days to remove the pages from its search index but has yet to take down the approx 30 photos from image search (over 2 weeks.)
I have sent several requests via Bing Webmaster Tools and last week sent a C&D. No reply... the photos remain and when the "source" link is followed they get the server's 410 Gone response.
Anyone else have problems getting images taken down from Bing and what finally worked?
