As Blogger continues to detect and remove more abusive blogs proactively, we're seeing a gradual shift from blatantly abusive blogs, to blogs that, 5 years ago, would not have been righteously considered to be a problem . The decrease in abusiveness has several results. It's harder and harder to casually decide if a given blog needs to be reviewed - and if it's likely to be restored. Blogs which are marginally - instead of blatantly - abusive are more likely to be subject to repeated classification and review. The owners become less patient with reviews, as they endure each successive review. Which ever the possibilities for a given blog, when review is requested, this will require changes in the final review process.
