Marking a blog as Spam does what?

Got couple of blogs created that look like they are not from my target market. Hair growth products and fire alarm companies may employ accountants, but they may not be the ones creating the blog.

So, rather than just delete them, I'd like to know if marking them as "Spam" will give them a chance to contact me before deletion.

So, what happens when I click the "Spam" link on the "Blogs" page?
