Does Your Website Need CAPTCHA?
Introduction
Many business website owners face a challenging problem: how to enable visitor feedback without inviting a flood of spam. Posting your email address online often leads directly to spam because bots routinely scan websites to extract and misuse email addresses.
Protecting Your Email
To combat this, various techniques can help obscure your email from bots. A popular method involves using JavaScript to piece together the email address when a webpage is displayed, ensuring no valid email is visible in the source code. While effective, this approach isn't foolproof against all spam.
Another strategy is to avoid posting your email directly. Instead, provide a feedback or guestbook form on your website. This form uses server-side scripts to process input and send messages to you, keeping your email address hidden from visitors and bots alike. However, even these forms can be targeted by automated spam submissions.
The Role of CAPTCHA
A more secure solution involves using CAPTCHA alongside these forms. CAPTCHA stands for "Completely Automated Public Turing test to tell Computers and Humans Apart." Developed and trademarked by Carnegie Mellon University in 2000, CAPTCHA ensures that the web form is being filled out by a real person and not an automated program.
Typically, CAPTCHA involves showing users distorted letters or numbers that they must correctly type before submitting a form. This visual challenge is simple for humans but difficult for bots to decipher, reducing the risk of automated spam.
Benefits and Integration
Integrating CAPTCHA offers a reliable way to ensure that form submissions come from humans. Such tools are no longer limited to major websites; they are increasingly common across the web. Many programming languages offer easy integration options.
