We all want to avoid being spammed but at the same time we want to reveal our email address to people who need to contact us.recaptch solves that problem very easily and just by adding about 4 lines of code you can hide your email address from spammers and reveal it.
Another cool benefit of recaptcha is that you are helping "reading" books that is when some books have faded and are being scanned , you are helping solve the faded text.Read more about it on their website.
