To address this, Blogger Team have integrated Google’s spam filtering technologies into the Blogger comment system. Some of Blogger user will notice the new “Comments” tab. (Note: Blogger Team are gradually rolling this out to all users, so some of you may not see the new Comments tab yet.) In the Comments tab, there is a Spam sub-tab that shows all the comments that are likely spam.
The comments in the Spam inbox are not visible to readers. So, you can permanently delete spam comments by selecting them and choosing Delete. You can also mark comments as Not Spam that have been incorrectly classified as spam (what we call the “false-positives”). Choose Not Spam and the selected comments will be moved out of the spam list and will be immediately published on your blog.
Yes this is like an Akismet on Wordpress. Now Blogger user can filter which real comment or spam comment.
