I have mentioned in previous blog post that we were getting a lot of spam for ALTASO WordPress blog. Since August 2010 until February 2011 we received about 1500 spam comments. Since “Invisible Captcha” installation amount of spam comments went down dramatically. There are still some spam comments going through but now it is much easier to manage them. Our number is about 5-10 spams a month.
This blog post is about Invisible Captcha WordPress plugin we are using and are really happy for now. This plugin is smart invisible captcha for wordpress comments. More information about this plugin you can find here: http://wordpress.org/extend/plugins/invisible-captcha/
Plugin is written by Andrey Sorvin and is really good and free anti spam solution. Visitors of your website don’t need to enter letters and numbers, because captcha is not visible. Author claims that this small plugin automatically 100% protects your website from spam in comments … we thing it is somewhere around 98%

WordPress comments & spam
We have been running this blog powered by WordPress for couple of months now. After couple of weeks we started to receive spamming comments from people who probably things that they are going to have some linking from this site to theirs. Unfortunately for them this is not happening because all comments are moderated and most of the spam comments are deleted.
We do have plenty of spam comments for example:
WordPress is coming with Akisment plugin installed by default. “Used by millions, Akismet is quite possibly the best way in the world to protect your blog from comment and track-back spam. It keeps your site protected from spam even while you sleep. To get started: 1) Click the “Activate” link to the left of this description, 2) Sign up for an Akismet API key, and 3) Go to your Akismet configuration page, and save your API key.”
When following the steps in description above, we find out that Akisment is free only for personal blogs with multiple limitations as well. Because this is small business blog we would have to pay $5 every month for Akismet API key and usage of this service. Price might be reasonable because will save time going through spam comments. But we would like to find a free solution.
We have decided to search WordPress plugins for two relevant keywords: “spam” and “captcha”. Both those keywords returns multiple result of available plugins. After reviewing and reading about few of them we have decided to try Invisible Captcha – Smart invisible captcha protects your blog from spam comments. We are going to use it for some time and see if number of spam comments will decrease.
