Implementing Google reCaptcha

Overview
Google reCAPTCHA uses an advanced risk analysis engine and adaptive challenges to keep malicious software from engaging in abusive activities on your website. Meanwhile, legitimate users will be able to login, make purchases, view pages, or create accounts and fake users will be blocked.
Implementing this service in your application sign up flow will ensure that no bots are creating accounts.
