Update activity
How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.
Release cadence
No release in a yearHow often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Estimated value
What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.
Est. annual revenue
Est. acquisition value
No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from. A declining trend compresses what a buyer would pay.

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

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.

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

Больше года не знаю, что такое спам-комментарии! Имел опыт с большими плагинами спам-коммент. – одни проблемы и заботы: то надо решить спам это или нет, а потом удалить спам. С этим плагинам “Kama SpamBlock” не чего делать не надо – просто нет спамов!!!

Меня замучили китайцы со своим бесконечным спамом. У меня стоял акисмет, который действительно отмечал его, как спам, но приходилось регулярно вычищать тонны спама. Но когда я поставила этот плагин, спам вообще перестал приходить! Насколько я поняла, плагин что-то такое делает, что для отправки сообщения нужно выполнить мышкой нажатие кнопки. А боты этого делать не могут. Я редко захожу оставлять комментарии, но тут не удержалась, хочется сказать спасибо автору. И еще, хотя, написано, что с моей версией вордпресс плагин не тестировался, он все равно работает.
