Captcha is Evil! Solution for JoomShopping, Virtuemart and com_contact

Everyone knows, the lesser fields are required to fill during the registration process the higher conversion is. But what to do with bots which have been signing up on our site? To add Captcha? It’s a paradox. Below you will find a simple yet nice solution allowing you to prevent bots' submissions without Captcha.

What bots are doing? They’re submitting registration form. And what site developers are doing to prevent the registration on direct link? They adds so called token field with random name to the field. The solution: during page rendering on client side we must display the form without token field (without our random name). But after full page loading (to this moment the bot ate the page) we create a token field in the form using special script. Or, it’s better to say, not create, but assign a correct random value to the script.
