Answer 1

The captchas seem to be fooled by adept people. The Akismet is better option in my view. Having said that you should still use captch along with Akismet :)

Answer 2

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.

Answer 3

You'll never be able to completely avoid spam, but most fully automated spambots can be stopped by something like ReCaptcha.

Answer 4

Best captcha solution i know so far is Recaptcha (same used in stackoverflow).

if you want more security, you can build your own verification system.

Answer 5

no captcha aren't failure proof. I also heard that people from for example India solve captchas for a little bit cash. The best way to stop spam is a multitude of:

• captcha: proof that user is human(some bots are able to crack them. The harder the captcha the harder to crack)
• akismet: test text for spam. I believe sometimes message get through(The call it ham or something)
• authentication: when you authenticate that user is legitimate, I think you can stop spam completely. For example say a user is trusted when he has posted 5 spam-free posts.
