Well, I was trying to find a good and completely effective anti-spam plugin for my wordpress blogs but still I am not able to find any good comment ant-spam plugin. I have been using the Askimet but it seems like many spams do get pass through its filter and I still get a lot of spam comments every single day. Now, I have also used the Bad Behavior Plugin for wordpress and that too seems not working fully. I get lot of comment spam even when it is installed and that’s quite weird.

Another anti-spam plugin I have been using is the Mathematical challenge plugin where you have to enter the result of some simple mathematical calculation. That was good for some days but seems like the the comment spammers have now built up a workaround for that too. I start getting comment spam again and this is driving me crazy. I am right not on Comment Karma and I think this one should work well as I really need to stop this comment spam. If you have any suggestion, I will love to hear from you.
