Slickhouse has been live for almost a week now and I'm yet to receive a spam comment. In comparison, each time I logged into the WordPress Admin on v8 of the site, I was greeted with over 200 spam comments to moderate, that Askimet had trapped.
So it seems that OpenCAPTCHA is working as intended and preventing spammers from submitting comments.
When selecting a Captcha provider for SlickCMS, I had several criteria including:
- Free
- Easy to implement
- Easy to use
- Reliable
OpenCAPTCHA was the only one I came across that met all my requirements. Although no formal sample code is provided in ASP (SlickCMS' language of choice), the PHP code was easy enough to grasp and develop the same.
So, if you're looking for a spam prevention tool for your next web project, consider OpenCAPTCHA.
