The big number of spam comments in my Nucleus blog was the last straw to move to WordPress. WordPress has an effective mechanism to filter spam: approval comments or permit to add comment only for registered users. Also, there are existing different plugins for this purpose. I used the first approach and I was enough for me till spammers became much more intense last week. So, I decided to install Spam Karma 2 plugin for by blog. It’s amazin tool! I just made initial configuration and that’s it! Now Spam Karma does my work. It analyses and makes decision approve a comment or mark it as spam. One a day Spam Karma sends me report by email about work which was done. Thanks a lot to Dr Dave. Excellent work!
