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

Answer 1

I do not believe that there is 100% spamproof captcha and it is wrong to count on this.
But I believe in captcha being capable to change its principles of spamstoppingn more fast and easy than spamming techniques development.

PS
The most popular captchas (reCAPTCHA, SI Captcha, etc.) do not and cannot be changed, are passable by bots .
