Any website that provides a form, whether it be a shopping cart form, a registration form, or a feedback form like this one, carries the risk of having malicious persons fill in the form with data other than intended. Often this is done by the hackers creating automated search programs, called bots, that find vulnerable forms and use them to hijack the form for to vandalize the site or other purpose. My question here is an admittedly weak version of ensuring that a human is filling out my form, not a bot.
