Bots have been around for awhile and have be an ever increasing concern. How do you know if an account was created by/for a bot or by a genuine user? There different ways to confirm somones humanity, but a great solution is to use CAPTCHA. It asks the user to look at the image and input the letters presented. A human should have little to no trouble copying the letters, however a bot will more often then not be completely dumbfounded. CAPTCHA’s distort the text of the image making it even harder for bots to answer it correctly.
