very good antispam

Better than reCaptca
By , for WP 3.8

When I use si Captcha I was getting several dozens of registered user per day.
I used another plugin (s2member) that requires (if you use there pro forms and use their s2member pro) to use reCaptcha.

My registrations have dropped to two per day. Even I get locked out because of too many failed attempt to login to my own site.

I wish s2member would switch to si Captcha on the preforms.. anyone that would say otherwise may be loosing a ton of registrants and money.

Ich liebe es - i love it

Works, easy to use if you want to use it on all your comments, forms, etc. I only use it for my login form as I sue another for comments and such. But it was great to have the choice to just use it for my login. With several bloggers having access I need to know there is another level of security besides them using a too simplistic password.

It works, its free, and supports BuddyPress!

I have the latest WordPress with the latest BuddyPress and I really needed a Captcha system to stop all these spam bot registrations that I was constantly removing. I tried a bunch of different Captcha plugins. Some didn't work in BuddyPress, some broke my pages, others seemed to do nothing at all. But this plugin right here did the job for me. No fuss. It integrated nicely with the BuddyPress registration/etc. Has enough configuration options to rival some pay plugins. If you want to donate money, this guy deserves it. This plugin stopped the spam bot registrations almost completely and made my member management so much easier. I'm grateful for true open source developers.

Small, simple and works without scamming you for your e-mail etc

This is one of the few CAPTCA plugins that doesn't scam you for your e-mail by demanding registration, additional library downloads and other nonsense.

Thank you

The only plugin that worked on the theme i'm using! It's not google captcha, but it does the job!

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...
