WPshore Contact Form 7 Spam Prevention is an addon for the Contact Form 7 plugin. It helps you thwart spambots without using captcha by marking mesaages with multiple URLs as spam.
If the user enters more than specified number of URLs in a Contact Form 7 it will display the spam message. You can change the number of allowed URLs in the shortcode.
Eg. [preventspamurl allowedurl value:2] value:2 means the user is allowed to specify upto 2 URLs while filling up the form. In case more than 2 URLs are added, the message will be marked as spam.
