Overview

Effectively prevent automatic spam when a spam comment is posted with Kama Spamblock, a plugin that operates discreetly and remains completely invisible to users—no captcha codes required. The plugin not only blocks spam comments but also conducts thorough checks on pings and trackbacks to ensure the authenticity of backlinks.

Even if you are using an external comment system like Disqus, installing Kama Spamblock remains valuable. This is because autospam can be posted directly to the ‘wp-comments-post.php’ file, and the plugin serves as a robust defense against such comments.

Безусловно лучшее решение для борьбы со спамом на сайте, но когда ждать обновления?

Хороший плагин

Спасибо за плагин. Хорошо работает. Блокирует автоматический спам и пропускает нормальные комментарии.

in a year and a half, not a single spam comment and captcha not annoys

by Vladimir Kazakov·5 years ago

En:
On the themes-wordpress.ru site with zero visitors I have about 700 spam comments for a year of work, which Akismet marked as spam, they had to be opened and cleaned. This is a waste of time. It is better that spam comments do not appear at all.
right now I use the kama-spamblock plugin and in a year and a half not a single spam comment! kama-spamblock is a very good plugin!
Another advantage is that captcha does not annoys. no need to enter any numbers or click (like in Google recaptcha).
Right now I want to repeat your success (take over the idea of captcha) for another CMS. everything is so great.

Ru:
за полтора года ни одного спамного коментария и капча не раздражает
раньше у меня на сайте themes-wordpress.ru с нулевой посещалкой за год работы были штук 700 спамных коментариев, которые Akismet помечал как спамные, их надо было открывать и чистить. Это бессмысленная трата времени. Лучше чтобы спамные коментарии вообще не появлялись.
щас я пользуюсь плагином kama-spamblock и за полтора года ни одного спамного коментария! kama-spamblock – очень хороший плагин!
Ещё одно преимущество в том что капча не бесит. не требуется вводить никакие цифры или кликать (как в Гугл рекапча).
Щас я хочу повторить ваш успех (перенять идею капчи) для другой CMS. настолько всё отлично.

Отличный плагин! Рекомендую!

Мне очень нравятся плагины, которые имеют минимум настроек и выполняют то что от них нужно без излишеств. Спасибо!
