How does it work?

Users users will have to pass the Secure Image CAPTCHA test. They are shown an image with a code, then they have to enter the code in the form field before the click submit. If the code does not match, the form will return «Incorrect CAPTCHA».

What are spammers doing anyway?

Human spammers

They actually visit your form and fill it out including the CAPTCHA.

Human or Spambot probes

Sometimes contain content that does not make any sense (jibberish). Humans or Spam bots will try to target any forms that they discover. They first attempt an email header injection attack to use your web form to relay spam emails. This form is to prevent relaying email to other addresses. After failing that, they simply submit the form with a spammy URL or black hat SEO text with embedded HTML, hoping someone will be phished or click the link.

Blackhat SEO spammers

Spamming blog comment forms, contact forms, Wikis, etc. By using randomly generated unique «words», they can then do a Google search to find websites where their content has been posted un-moderated. Then they can go back to these websites, identify if the links have been posted without the rel=»nofollow» attribute (which would prevent them contributing to Google’s algorithm), and if not they can post whatever spam links they like on those websites, in an effort to boost Google rankings for certain sites. Or worse, use it to post whatever content they want onto those websites, even embedded malware.

Human-powered CAPTCHA solvers

Довольно легко нанять человека для распространения спама. Обычно это стоит $0,75 за 1 000 спамерских сообщений. Спамер даёт нанятому список сайтов и что писать на них, после чего тот начинает спамить по этому списку. Не весь спам (и другой мусор) генерируется компьютером с помощью ферм CAPTCHA или прокси. Плохие парни могут иметь реальных людей, которые спамят вам. Ферма CAPTCHA содержит большое количество дешёвой рабочей силы (Индия, дальний восток и т. д.), которые разгадывают CAPTCHA. CAPTCHA прокси — это когда ваша CAPTCHA показывается посетителям других сайтов: порно, игровых и т. д. После решения CAPTCHA на этих сайтах они пишут спам на ваш сайт.

Спамеры как-то проходят CAPTCHA. Что я могу сделать?

Make sure you have configured the settings page and enabled the CAPTCHA on all your forms.

The CAPTCHA will not show to logged in users posting comments if you have enabled this setting: ‘No comment form CAPTCHA for logged in users’. Enable this setting if a logged in user is the spammer.

Check for a plugin conflict.
A plugin conflict can break the validation test so that the CAPTCHA is never checked.
Be sure to always test all the comments, login, registration, and lost password CAPTCHA forms after installing or updating themes or plugins.

Troubleshoot plugin conflicts, see troubleshooting below.

Sometimes your site becomes targeted by a human spammer or a spam bot and human captcha solver. If the issue persists, try the following suggestions:

Попробуйте разрешить комментирования только зарегистрированным пользователям, или включите модерацию комментариев. Больше информации на Combating Comment Spam.

I made another plugin with Google No CAPTCHA reCAPTCHA that has realtime bot detection. You can uninstall this plugin and try my new plugin Fast Secure reCAPTCHA

Как я могу поменять цвет поля ввода CAPTCHA в форме комментирования?

Если вы хотите узнать, как настроить цвета в форме ввода captcha See this FAQ

Troubleshooting the CAPTCHA image or form field does not display, or it does not block the form properly

Another plugin could be causing a conflict.
Temporarily deactivate other plugins to see if the CAPTCHA starts working.

Your theme could be missing the wp_head or wp_footer PHP tag. Your theme should be considered broken if the wp_head or wp_footer PHP tag is missing.

Do this as a test:
In Admin, click on Appearance, Themes. Temporarily activate your theme to one of the default default themes.
It does not cause any harm to temporarily change the theme, test and then change back. Does it work properly with the default theme?
If it does then the theme you are using is the cause.

Нет картинки CAPTCHA и поля ввода в форме комментирования?
Возможно, в вашей темы некорректно написан файл comments.php.

When diagnosing missing CAPTCHA field on comment form….

Make sure your theme has <?php comment_form(); ?>
inside /wp-content/themes/[your_theme]/comments.php. (look inside the Twenty Ten theme’s comments.php for proper example.

Make sure that the theme comments.php file contains at least one or more of the standard hooks:
do_action ( ‘comment_form_logged_in_after’ );
do_action ( ‘comment_form_after_fields’ );
do_action ( ‘comment_form’ );
If you didn’t find one of these hooks, then put this string in the comment form:
ID ); ?>

The CAPTCHA and input field does not display on JetPack comments form

If you have JetPack comments module enabled then captcha/recaptca/anti-spam plugins will not work on your comments form because the comments are then loaded in an iFrame from WordPress.com The solution is to disable the comments module in JetPack, then the CAPTCHA plugin will work correctly on your comments form.

Troubleshooting if the CAPTCHA image itself is not being shown on the comment form:

By default, a logged in user not see the CAPTCHA on the comment form. If you click «log out», go look and it should be there. Make sure you have configured the settings page and enabled the CAPTCHA on the comment form.

If the image is broken and you have the CAPTCHA entry box:

Это может случиться, если у сервера неправильно настроены права доступа к папке, либо если неправильно настроен URL WordPress.
или адрес блога (URL) установлен неправильно в настройках WordPress («Настройки» / «Общие»).

See FAQ page on fixing this problem

Кнопка обновления CAPTCHA не работает

Your theme could be missing the wp_footer PHP tag. Your theme should be considered broken if the wp_footer PHP tag is missing.

All WordPress themes should always have <?php wp_footer(); ?> PHP tag just before the closing </body> tag of your theme’s footer.php, or you will break many plugins which generally use this hook to reference JavaScript files. The solution: edit your theme’s footer.php and make sure this tag is there. If it is missing, add it. Next, be sure to test that the CAPTCHA refresh button works, if it does not work and you have performed this step correctly, you could have some other cause.

CAPTCHA не работает, и я не могу зайти через форму логина.
