When a blog is rejected ("needs more work"), links pointing to it seem to end up in this page:
I think that's not helpfull, after all, last time the user clicked that link, it was perfectly valid. And using the search will not help her here, either!
Th liink should point to:
1. For the Author: to the blog (maybe in edit mode), so she can improve the content
2 For all other users: To something like: "This conten is not available right now, maybe check back later or contact the autor (Link)".
