Spam Karma is a WordPress plugin designed to feature anti-spam functionality to prevent comment spam on blog posts.
What makes SK2 stand out from other anti-spam plugins is its commitment to remaining unobtrusive. You won't have to worry about frustrating your readers with annoying CAPTCHAs or other obstacles that may discourage them from leaving comments.
One of SK2's greatest strengths is its lineage. It is the successor to the original Spam Karma plugin, and while it shares many of the same development ideas, none of the code is the same. This ensures that SK2 is a completely fresh take on anti-spam technology.
To use SK2, you'll need to have WordPress version 1.5.1 or higher, as well as mySQL version 4.0 or higher (though it's recommended that you use the latest versions of both). The plugin is free for non-commercial use, making it a great choice for bloggers who want to keep their sites free of spam without breaking the bank.
