Works fantastically well.

WARNING: Don't use this plugin on your login page!
By ,


If you use this plugin on your login page BEWARE. It will eventually crap out and prevent you from logging in. Your only recourse is to delete the Plugin Folder via FTP.

In addition it does not appear to block spam that effectively anyway. The developer continues to blame plugin conflicts, which could be true. But this is the second time its happend to me.

Doesn't work when a social media login plugin is activated
By , for WP 3.5.1

This plugin gave me so many problems because it couldn't work with my social media login plugin on my site. There is no way I can turn off my social media login plugin just because SI Captcha cant work when its on. So i had to look for another plugin instead.

Works like a charm

Works like a charm on Buddypress, shows up on custom register-forms as well as all the regular forms.

Quick, Easy, Straight In
By , for WP 3.5.1

The author of this plug-in has a grand total of three plug-ins published and I'm using all of them. Configuration has been easy in all cases, particularly with SI CAPTCHA Anti-Spam and, while the CAPTCHA itself may not be the most sophisticated in the world, if it works, it works (and it does, by the way) - if not, I haven't spent a whole lot of time setting it up and won't bewail the lost effort.
