CleanTalk Anti-Spam Protection
This website was inundated with over 500 spam comments a week before I installed CleanTalk Anti-Spam. I hadn’t noticed until there were thousands of them waiting to be approved, and it took me hours to go through and delete them all. I looked through the available WordPress Plugins and found CleanTalk and decided to give it a go – and I’m so glad that I did. Now I get an email once a week with a summary of the items they have blocked for me, which is usually 4-500. Their software analyses the comments and blocks comments that are generated by Spam Bots.
