Have you ever logged onto your email to find 20 WordPress comment moderation emails with comments that say exactly the same thing across all of your blogs?
- “Great post, I’ve bookmarked it!.”
- “Thanks for the information.”
- “I can’t figure out how to add you to my RSS reader.”
- “So nice to come across a post written with proper grammar!”
Etc. These are paraphrases of course, and sometimes they get more creative. A common denominator of these comments is that they are generic and could be left on any post, regardless of the content of the post. These comments are obviously not made by real people visiting your blog, they are made by spam robots. Occasionally when I am not sure if a comment is real or not, I Google the comment, in quotes. If I see the exact same comment has been left on several other blogs, I can guess it was probably a robot and not a person.
If you are using the Akismet plugin which comes with every WordPress install, this will help a lot. But it doesn’t catch everything.
You can mark each comment as spam, and block their URLs/emails/IP addresses in the “Discussions” area of your WordPress admin panel. That helps prevent the same spammer from commenting on that blog again. But, there always seems to be a new spammer on the horizon.
Here is a simple WordPress plugin I have begun to install in each of my blogs. I’ve been very happy with it. It definitely makes a big difference. It is compatible with WordPress 2.8 and doesn’t even require your blog commenters to fill in a captcha code (the funny letters you sometimes have to fill in to verify that you are not a robot). Instead, it works by creating fields for the comment robots to fill out, which no human being would see and fill out. It even tells you on your dashboard how many “bird-brained comments” it has caught. 🙂

I hope this helps!
