On my wife’s site, we were getting hit from numerous (15+) spam messages a day. We figured this was an acceptable number to just handle manually, but quickly grew tired of taking the time to moderate these comments, marking them as trash.
We tried various CAPTCHA plugins but none were very graceful. From difficult-to-read CAPTCHA strings to stark, unstyled “You have entered an invalid CAPTCHA” message, none of the CAPTCHA plugins we implemented really worked for us.
Then I found this plugin. It’s so simple in its implementation that it’s almost laughable. There’s beauty in what it does, though. It’s not overly complicated, it doesn’t affect the aesthetic of the site AT ALL, and most importantly, it just works.
I’ve had this plugin installed for over 10 years, 8 months and have only received 34857 spam comments. I give it five stars all day long.
