A common prevention method is to use a CAPTCHA on the page, which requires the user to type in a strangely lettered word displayed on screen. Another approach requires the user to listen to a word and then type it in. However, many people find such methods annoying, and companies often choose to deal with the spam rather than inconvenience visitors who are contacting them. See CAPTCHA and spambot.

This is an example of a forms page hit with spam that was sent back to the company.
