very good protection against spam.
It worked very well with buddypress. Many others wants money for that.
I am going to donate for this plugin.

Good one

I'd pose a 5 start obviously, but in some cases it misses some spammer account - but that's silly - it's actually a doing a nice work in both registration and login. Excellent one. Would like to recommend for any site. :)

Just what I needed - Thanks! :)

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.

Appalling
By , for WP 3.5.1

My old Captcha plug-in broke so I installed this one as an alternative. Annoyingly I went from getting a dozen or so spam registrations per day to getting hundreds. This plug-in attracted spammers rather than kept them out - almost as though that was the purpose it was designed for.

Far from me making a donation to the developers, I'm expecting them to chuck me a few bucks to compensate me for the time it's going to take to delete all these spammers I've now got in my MailChimp database.

Worked for a while but not anymore

Worked for a while but not anymore, now a robot creates ~10 users a day :(

Doesn't prevent spammer to register - Broken

The captcha can be broken by robots that register to my wordpress installation and try to publish articles.
