Easy to use and quite effective

I’ve been using this plugin for a couple of months now, I have also used other plugins from the same author as well. He has made a simple but yet very effective way to combat the form spam, I use contact form 7 and it integrates with that super easy. The spam has been 100% correct with no false positives. You can collect the spam if you want to double check but depending on your site that could be an endless job with the amount of spam some of my sites collect. I’ve been able to monitor real contacts from the forms, and I can only say that the spam that has come through has been delivered by hand and not via bot system.
