How to check if a comment is from a human:

There are several captcha variants out there for drupal. I use draggable captcha, as it is nicer than trying to decipher numbers or letters.

IMAGE OF DRAGGABLE CAPTCHA

Installation

Install and enable these two modules: captcha, draggable_captcha.

Configuration

go to
  configuration > people > CAPTCHA    
or navigate your web-browser to
  www.example.com/admin/config/people/captcha
and set the captcha settings as you desire.

Under
  people > permissions
  www.example.com/admin/people/permissions
there is the
  Skip CAPTCHA
option. There you can set which users (anonymous, authenticated, administrator) will not be offered a captcha.

Css problem

I had the problem that the draggable captcha image was not placed above the text that says
  Drag or click the correct shape to the grey "drop area".

see draggable_capture_wrong_css.jpeg.

So I added to the file
  sites/all/themes/responsive_blog/style.css
following line
  #draggable-captcha-mini label { float: none; font-size: 0.929em; }
I placed it after this line:
  .comment-form label { float: left; font-size: 0.929em; }
Then everything looks all right,
