As you've known that there is service Feed to Inbox. And many people use it on Blogspot for auto blog, many of them don't even delete the confirmed email from Feed to Inbox so we can get their feeded emails. You just send an email to feeded emails and bingo, your email with links will public immediately on their blogs. You can Google for email list with some FeedtoInbox footprints. Attached is the 180+ emails I just collected, just send an email. Hope to help. Drop me a thanks button if you see this useful. BR.
