if ($kirby->request()->is('POST')) {
    # Call security
    $form->spamWordsGuard();

    # .. more code
}

Configuration

You may change certain options from your config.php globally:

return [
    'tearoom1.uniform-spam-words' => [
        'addressThreshold' => 2, // the number of addresses like links and emails that are allowed, default 2
        'spamThreshold' => 8, // the threshold for the spam score, default 8
        'useWordLists' => true, // Use the default word lists, default true
        'spamWords' => [ // define your own spam words, the key number defines the weight of the words
            1 => ['promotion', 'free'], // weight 1, increases spam likelihood only a little
            6 => ['seo', 'marketing'], // weight 6, increases spam likelihood a lot
        ],
    ],
];

• The addressThreshold defines the number of addresses like links and emails that are allowed in the message. If the number of addresses exceeds this threshold, the form submission is blocked.
• If no addresses can be found, then the message is considered as safe and no spam words are checked.
• The spam score is calculated by counting the occurrences of spam keywords in the message. The score is increased by the weight of the keyword. If the score exceeds the spamThreshold, the form submission is blocked.
