Blogger Adds Spam Filter for Comments

Blogger's commenting system still needs a lot of work. Even though you can now display the comment box below the post, you can subscribe to comments by email and sign in using OpenID, the authentication procedure is still clunky, you can't reply to a message, read other comments from the same user or edit a comment after posting it.

The good news is that Google finally solved two big problems for Blogger authors: comment spam and managing comments. If Gmail has a great spam filter, why Blogger can't use a similar technology to detect spam comments?

"Blogger now filters comments that are likely spam comments to a Spam Inbox, much like the spam folder in your email. When someone leaves a comment on your blog, it will be reviewed against our spam detector, and comments that are identified as possible spam will be sent to your blog's Spam Inbox, found at Comments | Spam," explains Blogger's help center.


Blogger's spam filter works well and you can improve it by clicking on "Not spam" next to a false positive or mark as spam a message that hasn't been filtered.

Now it's easier to manage the comments from your blog even after they're published. The new Comments tab lists all the published comments and lets you delete them or mark them as spam. You no longer have to visit each blog post and manually remove spam comments.


Blogger's help center says that the Comments tab should be displayed even if you don't enable comment moderation. Unfortunately, the tab disappears when you disable comment moderation. As Blogger's blog admits, comment moderation can be annoying. "To fight spam, some of you enabled moderation of all comments or required word verification or login. While somewhat effective, these checks limit real-time conversations around your blog."

For now, I've enabled comment moderation for posts that are older than 30 days. Hopefully, you'll no longer see spam comments.

  1. At last! Some of the spam comments appeared even with captchas turned on, and it was incredibly obvious the comment was spam. Hopefully they finally get this issue resolved correctly.

  2. Really informative one .I Have one blogger blog as per my view i think the automatic spam filtering will reduce our job and we will get more time to work out on our content rather than reading and checking for spam comments.

  6. You can also use Comment SPAM Wiper. As I understand it has a high rate of detection and you can use the API with the vast majority of platforms.
