add_action('super_before_processing_data', function($atts){
  $data = $atts['atts']['data'];
  // Return fake message when one of the following fields matches the value
  $checks = array(
    'email' => array(
      'bot@bot.com',
      'bot2@bot.com',
      'bot3@bot.com',

  foreach($checks as $fieldName => $compare){
    // Skip if field with this name does not exists in the form
    if(!isset($data[$fieldName])) continue; 
    // Compare the entered value in the form with the one we defined
    if(in_array(trim($data[$fieldName]['value']), $compare)) {

        'error'=>false,
        'msg' => '<h1>Thank you!</h1>We will reply within 24 hours (fake message to pretent succesful submission, but nothing really happened)'
