Dead simple and super lightweight anti-spambot WordPress plugin. No captcha, tricky questions or any other user interaction required at all.
Installed and waited. Still received the same amount of spam as before but noticed it also started hiding the IP addresses in the spam section of my comments on the admin side. Removed and IP addresses are showing up again.
