One of the gravest problems that face bloggers today is the fact that with the increased popularity of blogs, the increase in spamming has also been phenomenal. Blogs are today the new rage of the internet, with everyone owning a blog as a medium of free expression. However, the spammers try and exploit most features of these blogs including the fact that most of these blogs are unprotected and free. These features help the spammers since they provide an easy and free platform for the spammers to promote and advertise their own products and websites.
For the blogger, these spam become impossible to remove since it is not possible to manually check every comment and then delete the spam ones. Spammers leave many messages every day, sometimes even multiple messages. Hence one needs an automated mechanism to delete and work with spam. Most of the plugins provided by the WordPress platform work well for the basic purpose but don’t tend to work as well when dealing with a barrage of spam. Hence we need to look at other plugins for better spam protection.
The best plugin for that purpose is the new and improved WordPress Hash Cash where the users are required a proof-of-work in order to confirm that the website was indeed viewed by some browser and not by an automated machine. It provides the admin with three different recourses for comments. The admin can either push the comment into a manual moderation queue or into the default Akismet queue which is the default mechanism. Or if the admin feels, the option of deleting the comment is also open.
