One of the difficult tasks in maintaining a blog is to delete spam comments regularly. As your blog gets more and more traffic, it becomes target of spam bots. Unless you have real good spam filters, even your moderately successful blog can be flooded with hundreds of spam comments in a day. For past few weeks I was busy preparing competitive exams and during this period my comment approval queue was more than 10000. Now as there was no feasible way to check all these comments to filter out genuine comments, I decided to clean the queue by deleting all the pending comments.
