• Hi.. cool plugin.. you say 100% effective? I can see why it would be effective with the captchas that are display in this format [] + 6 = 9 or 1 x [] = 5 because it is hard for a machine to copy and paste that into google… but for this format 3 + 3 = [] it is easy enough to get the answer from google very fast…

    So is this really 100% spam proof? Perhaps there is some other trick I am missing? The countdown timer is a great idea as it takes X amount of time to figure out the username and password but working out the maths problem with small numbers is very fast for a machine…

    I do think this plugin is a winner… I just wanted to know why you were confident enough to state 100% effective?
