I've tried several extensions to get spam under control, and though some have knocked the edges off the problem, every day I am still deleting many attempted registrations and some who manage to get themselves through the gauntlet of spam protection I have, get an automated mail approval, get in and plaster my site's forum with spam. I saw SiteBrains and thought it sounded promising, though I was hesitant to try without reviews to go on.
Immediately upon installing this extension, my site broke and I was unable to access either front-end or admin side of it. Two emails (through site contact page) to the developers went unanswered. Luckily my webhost helped me resolve the problem and get me back online... however, I have empty frames on two pages that have persisted since installation and subsequent damage control.
Sorry to report this... I was really hoping this extension would help me get control of spam. I'll keep looking.
