Email Address, How to keep web bots from collecting Options

[perkle]

Is there any way to keep the spamers or web bots from collecting my email address on contact page. I have seen at least one site where the mailto:emailaddress was done using ASCII Characters .

You can find many ways to do javascript email obfuscation. You can also create a response form that employs a Captcha or rudimentary Turing Test to keep out spambots.

using ASCII or UNICODE chars is not foolproof

using javascript to write ASCII/UNICODE characters into the page is pretty safe though

a couple of simple javascript functions to hide mailtos

CODE

function HideEmail(user)
// write email address on page to hide from 'spiders'
// recipient name passed as user.
// change domain name in this script before using on your site
{
domain = "domain.tld";

document.write('<a href=\"mailto:');
document.write(user);
document.write('@');
document.write(domain);
document.write('\">');
document.write(user);
document.write('@');
document.write(domain);
document.write('</a>');

}

function EmailName(user,PromptText)
// write email address on page to hide from 'spiders'
// recipient name passed as user. Friendly name passed as PromptText
// change domain name in this script before using on your site
{
domain = "domain.tld";

document.write('<a href=\"mailto:');
document.write(user);
document.write('@');
document.write(domain);
document.write('\">');
document.write(PromptText);
document.write('</a>');

}

the only safe way is to NEVER have the mail address in the page and use a form and server side code to send the email.
