socialmedialtd

A plugin developed by <a href="https://social-media.co.uk" rel="nofollow ugc">Social Media Ltd</a>, to prevent form submission when the message contains custom predefined words. Use as many stop words as you wish, and manage those easily through the settings page in the admin panel. When any WPCF7 form is submitted, textareas’ content is checked against those words, and if a hit is found, an error comes up, and the form submission is cancelled.
