CAPTCHA is very useful at this time to separate a robot from human for the right protection of a certain website. By distinguishing between humans and automated computers programs, CAPTCHA offers safety and security in a number of ways. First, it protects registration forms in websites as I've said while ago. It can also prevent spam comments, then it can also protects email accounts. Making online shopping will be more secured using this such. So in my opinion, CAPTCHA is very necessary.
