/**
|
|
* The SSAkismet class provides spam detection for comments using http://akismet.com/.
|
|
* In order to use it, you must get an API key, which you can get free for non-commercial use by signing
|
|
* up for a http://www.wordpress.com account. Commercial keys can be bought at http://akismet.com/commercial/.
|
|
*
|
|
* To enable spam detection, set your API key in _config.php.
|
|
* The following lines should be added to **mysite/_config.php**
|
|
* (or to the _config.php in another folder if you're not using mysite).
|
|
*
|
|
* <code>
|
|
* SSAkismet::setAPIKey('<your-key>');
|
|
* </code>
|
|
*
|
|
* You can then view spam for a page by appending ?showspam=1 to the url, or use the {@link CommentAdmin} in the CMS.
|
|
*
|
|
* @see http://demo.silverstripe.com/blog Demo of SSAkismet in action
|
|
*
|
|
* @package comments
