To delete a comment that is waiting to be approved, use the HTTP DELETE method.
Only the moderator or owner of the blog can delete a comment awaiting approval. Deleted comments cannot be restored.
See Authenticating requests
for information about how to authenticate the request.
To delete a comment awaiting approval, complete the following steps:
Retrieve the moderation service document. See Retrieving the Blogs moderation service document for more details.
In the service document, locate the workspace with the <atom:category term="comments-moderation" .../> child element, and then find the collection with the <atom:category term="approval-content" .../> child element, and make a note of the web address in its href attribute.
Send a GET request to the web address you copied from the previous step. In the returned feed, find the comment that you want to delete, and make a note of the web address for it, which is specified in the href attribute of its rel=edit link.
Send a DELETE request to the web address of the edit link of the comment that you noted in the previous step.
