Keeping up with comments can be hard enough without having to deal with spam comments. Most of these comments are from automated bots. There’s not a lot you can do about spam on Blogger, but there are some ways to help prevent it from happening.
Heads up! This post is no longer being updated, so some details may be out of date.
Prevent spam comments on Blogger without turning away readers
1. Who can comment? Turn off Anonymous
Settings > Posts & Comments > Who Can Comment…
By choosing either Registered Users or Users with a Google Account, the user has to log in or sign up to leave a comment.
The benefit here is that most bloggers will probably already be logged into their Google account, but by disabling anonymous it will stop fake accounts and robots from leaving a comment as they won’t register just to place a link.
2. Comment Moderation
Settings > Posts & Comments > Comment Moderation
Choose always or sometimes to moderate comments before they go live on your site. I’d recommend turning it on sometimes for posts older than # days.
Spam bots crawl you’re site and will more than likely comment on an older post, turning this on will notify you and won’t go live unless you approve it.
3. Install a Third Party Commenting System

Use Disqus or IntenseDebate for comments instead. These tend to get less spam in general. There is also an option to add “blocked” words that will go to spam if used.
You can also choose an option that if a certain amount of links are used, the comment will be marked as spam until you check it. I’ve used both, they are slightly different but both do a great job – my personal preference is Disqus.
You could also instal a Facebook Comment system on your blog which allows readers to comment via their Facebook profile.
4. Don’t be spammy
Don’t “spam” you’re own link on dodgy websites or forums. Spammers will easily find you on these sites and crawl your blog for an opportunity to leave a link. Although backlinks can help with blog traffic, not all links are valuable.
