It really helped to greatly reduce spam comments.

yes and no

I have been using this plugin for quite some time now and it prevents a lot of SPAM comments to be submitted - down from 10+/day to perhaps 1 every second week.

However, it does not prevent SPAM user registrations - at all. 10 new hotmail-users every day, I would be flattered if it were real persons...

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

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.

I Love this plugin
