## Description

#### Algorithm

 1. Plugin generates token on the backend side.
 2. Plugin adds hidden field for token in each form which will use method “POST” after
    rendering of the page.
 3. Plugin inserts token in the field after user’s interaction with site.

#### For developers

Antispam will automatically check submissions of the regular forms but ignores all
AJAX requests.
 If you want to change this behaviour, you can use filter `concise_antispam_need_to_validate_token`.
See example:

_Disable Antispam for some forms:_

    ```
    add_filter("concise_antispam_need_to_validate_token", function($needToValidateToken) {
        if (!empty($_POST['do-not-check-antispam-token'])) {
            $needToValidateToken = false;
        }

        return $needToValidateToken;
    });
    ```

You can also always manually call `\Concise\Antispam::validateTokenOrDie()` in your
custom handler.

### Formidable Forms integration

For proper work disable the honeypot checking in the forms

## Installation

 1. Upload plugin to plugins directory

Thank you so much for this plugin. I didn’t notice the email attack on my client’s
web site until 490,000 messages had been blocked and quite a few had gotten through.
The number was increasing by about 3000 per minute, and after enabling this plugin,
the incoming messages were just STOPPED, INSTANTLY.

Works like a charm. It doesn’t slow down the page at all and catches all spam with
incredible accuracy—I haven’t had to delete a single spammy message since installing
it. Excellent work!
