Effective Anti-Spam in WordPress with Plugins

WordPress has a very rich set of plugins and a combination of them can make anti-spam in WordPress quite easy. Here is a list of plugins that can help prevent spammers from registering spam account (if the site allows registration of new users) and posting spam comments.

Anti spam comments

Use the Akismet WordPress plugin.

Akismet is a Web service that automatically detects comments and trackback spams. The Akismet WordPress plugin checks the comments against the Akismet web service to detect and block spams.

Anti spam user registration

Use the Math Captcha WordPress plugin.

The Captcha plugin allows you to protect the website from spam by asking the users to do a math calculation in the login, registration, password recovery and comments forms.

Anti brute-force password cracking

Use the Limit Login Attempts WordPress plugin

WordPress allows unlimited login attempts by default which allows passwords (or hashes) to be brute-force cracked. The Limit Login Attempts plugin temporarily blocks the Internet address after a specified limit on retries from that IP is reached, and makes the brute-force password cracking difficult.

With these plugins, the WordPress installation should be able to handle most of the spams seen by small sites.
