If you have had a blog for any time at all, you are well aware of the spam comments situation that exists will all forums and blogs.
While there are many solutions out there, I will try to highlight the ones that I have personally used and my experience with them.
1 ) AVH First Defense Against Spam
Link: http://wordpress.org/extend/plugins/avh-first-defense-against-spam/
AVH F.D.A.S. does a good job of preventing spammers from ever reaching any other plugin, and sometimes before even seeing the comment form. It works off of the “Stop Forum Spam”, “Project Honey Pot”, and “Spamhaus” blocklists. These blocklists help to identify previous spammers based on an IP address. If the visitor’s IP address scores high enough, it will be blocked. All of these settings are configurable for sensitivity. With any plugin that uses a blocklist, there is a possibility for false positives. I have not experienced this myself yet, and this plugin is #1 right now for my needs in preventing spam.
2 ) Akismet
Link: http://wordpress.org/extend/plugins/akismet/
Akismet still does a decent job of preventing spam, as is by far the most widely used plugin because it ships with most WordPress installs. It uses a score based system to identify spam based on visitor’s IP address, name, comment text, and probably some other identifiers as well. It does a pretty good job when used alongside of another plugin.
3 ) Defensio Anti-Spam
Link: http://wordpress.org/extend/plugins/defensio-anti-spam/
This plugin claims that it needs to be run stand-alone from other plugins. With my experience, it makes no sense to run Akismet and Defensio together since they both use the same type of algorithms and API to determine spam. I’d turn off Akismet when using this, but it could be used fine with most other plugins that do not use a scoring system to identify spam.
4 ) WP Recaptcha
Link: http://wordpress.org/extend/plugins/wp-recaptcha/
Nothing thwarts comment spam bots like a good CAPTCHA system. This plugin adds a human input check on your comment form that must be correct before the form can be submitted.
5 ) Growmap Anti Spambot Plugin (G.A.S.P.)
Link: http://wordpress.org/extend/plugins/growmap-anti-spambot-plugin/
The idea behind this plugin is simple. It adds a checkbox that the user must check before they can submit the comment form. If bots try to submit without it being checked, they will be stopped on the server-side as well. Overall, this does a very good job of preventing automated spam bots. CommentLuv Premium includes this plugin as part of their paid plugin.
That’s it.. If there was a combination that I would use, I would pick AVH First Defense Against Spam and the Growmap Anti Spambot Plugin. If you wanted to be extra careful, you could include WP Recatpcha and then Akismet or Defensio for a final layer of defense. As always, when running more plugins, it does have a tendency to slow down your blog and admin dashboard as well.

I think two of the well-known anti spam plugins are akismet and growmap anti spambot plugin. These two are really great plugins to control those spam comments thrown all over the net. Moreover, having your own plugin is a must to protect your interest on your own site.

A friend of mine also recommended AVH F.D.A.S. but is it me or it has a problem? It’s not showing up in WPMU DEV Updates. Did anyone face a similar situation?

Do any of these include trackback spam filters? Akismet used to do the job, but I have so many sites, plus client sites, it would get expensive… I started using a combo of Spam Free for comment spam + Bad Behavior for trackback spam. Spam Free no longer works & the second I uninstalled it I got 4 spam comments. Im looking for an all in one block for comment + trackback spam. Cant seem to find it.
Preventing spam has become one of the top most priorities among the webmasters around the world. Ad these tools are great help regarding that issue. In my wordpress blog I am currently using the Akismet plugins and it is doing fairly good jobs and reducing my work load of removing spam manually.
Spamming is one of the major problem of the bloggers and webmasters but spamming is done by the bloggers and webmasters as they hope to get backlinks or traffics .My experience says that spamming never helps any more.

Nice tips. Growmap also have their own plug-in? That’s cool. I thought commentLuv is also included in this list but it looks like it’s under Growmap. Anyway, thanks for the tips.
