CAPTCHA

Captcha is a program that most websites use. Its use is to stop robots spamming blogs and other websites. I have Captcha on my blog, in fact our whole class has it. Captcha uses old books, newspapers and radio broadcasts for its words. It scans the books and other stuff and usually the words come out all weird and strange. About 200 million people solve these words every day. I think Captcha is a good thing to stop bots and other people from spamming. I also thing websites like Facebook  should use it as well.
