I have a Wordpress blog and the only user input is the commenting system. I want to totally avoid spam comments. Wordpress comes with Akismet but I can also use Captcha. Whi
No, captchas are not foolproof, so I would definitely recommend you ALWAYS use akismet when allowing comments in WordPress. Akismet will not catch everything either, so the only REAL solution is to moderate your comments. I've found Akismet + moderation to be a nice combo, however. Akismet catches almost everything, and when it doesn't, I usually only have to click the "check for spam" button again when I reach my comments page, and it's been marked as spam in the time between getting my moderation email and getting to the WP comments page.
