Alternatively, if you do have a lot of content, you can tag this thread with modlook in the sidebar and Staff can empty the whole blog for you. That will remove all data including posts, pages, tags, categories, comments, and uploaded files and once deleted, the data cannot be recovered. If you are sure you want Staff to proceed, please reply to confirm the URL of the blog you want them to empty.

IMPORTANT NOTE: Deleting blog content does not remove it from the SERPs (search engine page results). Google and Bing only clear their caches of deleted indexed content that produces a 404 (page not found) every 3 - 6 months.
