WordPress anti-spam plugin: Use Spam Karma

Dealing with spam can be quite a pain for owners of WordPress blogs. If you have an active blog, sooner or later you will have to start dealing with the fact that there are various ways to generate spam, and you have to deal with this spam. Soon, you will end up with so much spam that you will not be able to find genuine comments. However, there are ways around this. WordPress comes with a default plugin called ‘Akismet’ that needs to be activated in order to block Spam. Akismet needs a user to have an account on WordPress.com in order to be activated.
However, there are users who sometimes find that Akismet generates false positives (cases where a comment is mistakenly flagged as spam). False positives are the hardest to track, since these can get lost among the spam, and if you have a large number of spam, then you will lose valid comments. So, if you are looking for an alternative for using Akismet, then another plugin that is pretty famous is called ‘Spam Karma 2’ (link to download page). From the site:

Spam Karma is a modular system for detecting and blocking comment spam. It works through the use of various plugins that each test a comment for a particular aspect of “spamminess”. Each of these tests assigns points to the comment, and after all the tests are run they are totaled up. if the overall points are negative, it’s considered spam and blocked.
There are a lot of options for how you want the system to interpret the points and so forth. You can set the relative strength of each test individually, making some tests more important than others. There are third-party plugins available as well, which add functionality beyond that of Spam Karma alone.
