DISCLAIMER: THIS ADD-ON IS NOT AFFILLIATED IN ANY WAY TO AKISMET
Connect your Concrete5 website to Akismet; the most powerful anti-spam service out there, and say goodbye to spam for good.
This add-on installs an anti-spam service for Concrete that uses Akismet to check wether data submitted through forms on your website is spam or not. You can also flag messages as spam. It installs as a service according to Concrete5's standards, meaning you can activate and configure it through the dashboard under: dashboard > system > permissions > antispam.
Of course you can use Captha on your forms to avoid spam but this doesn't always work and some people think it's ugly. It also makes it harder for users to fill out a form as it's more work and they often get the captcha wrong. So for site owners that don't like to use Captcha, this is a great solution.
Installation and configuration is very easy and requires no programming knowledge.
This add-on is available for Concrete5 version 8.2 and above because unfortunately there's a bug in Concrete versions prior to 8.2.
You will need to register with Akismet and obtain an api key in order to use this add-on.
