Adds CAPTCHA anti-spam methods to WordPress on the forms for comments, registration, lost password, login, or all. For WP, WPMU, and BuddyPress.
It really helped to greatly reduce spam comments.
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 fantastically well.
Plugin recommend. Good block against spam.
Easy to get started with, and works well!
This plugin helped me to stop spam On all of my Blogs and Wp Installations.. Its Small, Unobtrusive and simple. Works. Thanks.
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.
Thank you for great work. I Love it.
Keep your hard and great work.
