The Internet is full of bots. There’s no denying it, bots have been created to perform tasks on the Internet for many purposes, a good example is Ticketmaster, who have calculated that approximately 60% of all bookings are made by bots (src nyt).
One of the most common practices for fighting back against bots is by adding what is known as a ‘Completely Automated Public Turing test to tell Computers and Humans Apart’ or CAPTCHA for short. These are commonly either an image or audio clip with letters and numbers that the user has to type into the computer to prove that they are human. One of the most popular versions of the CAPTCHA is reCAPTCHA, which is provided free of charge by Google, this is what we will be using to add a CAPTCHA to our registration page, to avoid bots registering for our website.
