Email obfuscation is a technique used to hide email addresses from web scrapers and spammers by converting them into a format that can be easily read by humans but is challenging for automated bots to recognize. One common way to obfuscate email addresses is by using JavaScript to dynamically assemble the email address on the client side. Here's a simple example of an email obfuscation script:

<!DOCTYPE html>
<html>
<head>
<title>Email Obfuscation</title>
</head>
<body>
<!-- Place this div where you want to display the email address -->
<div id="email-container"></div>
<script type="text/javascript">
// Define the email parts
var user = "contact"; // Replace with the user part of your email
var domain = "example.com"; // Replace with your domain
// Create an array to store the email characters
var emailCharacters = (user + "@" + domain).split("");
// Obfuscate the email address
for (var i = 0; i < emailCharacters.length; i++) {
emailCharacters[i] = '&#' + emailCharacters[i].charCodeAt(0) + ';';
}
// Create a mailto link
var emailLink = '<a href="mailto:' + user + '@' + domain + '">' + emailCharacters.join('') + '</a>';
// Display the email address
document.getElementById("email-container").innerHTML = emailLink;
</script>
</body>
</html>
This script creates a mailto link with the email address obfuscated using HTML character codes. When a user clicks on the link, it will open their default email client with the obfuscated email address, making it harder for bots to scrape.
Keep in mind that no obfuscation technique is foolproof, and determined spammers may still be able to extract email addresses from your website. Additionally, obfuscation can make it more challenging for users with screen readers or other accessibility needs to access your contact information. It's a good practice to balance email obfuscation with other spam prevention methods, such as using CAPTCHAs and maintaining a good spam filter.
