It’s true but everybody knows how annoying CAPTCHA can be. Besides, it fails to work very often. So, you can loose your clients in this way. As a webmaster I recommend to use spam protection that would be invisible for visitors. For instance, https://cleantalk.org/ uses simple plugins for the most popular CMS such as WordPress spam protection plugin, Joomla, Drupal and other plugins. In this way visitors will be more loyal and not annoyed guessing characters or puzzles.
