| Using
JavaScript to Create E-Mail Links! |
The clickable
links below were created without the use of "mailto" links.
By using Java-
Script to "hide" the links, you stop web spiders from harvesting
your e-mail address. |
| E-Mail Link Created
from JavaScript Code |
| Sample 1: |
<script language=javascript>
<!--
var username = "username";
var hostname = "yourdomain.com";
var linktext = "Click Here To Send Me Email";
document.write("<a href=" + "mail" +
"to:" + username +
"@" + hostname +
">" + linktext + "</a>")
//-->
</script> |
|
| E-Mail
Link Created from JavaScript Code |
| Sample 2: |
<script language=javascript>
<!--
var username = "username";
var hostname = "yourdomain.com";
var linktext = username + "@" + hostname;
document.write("<a href=" + "mail" +
"to:" + username +
"@" + hostname +
">" + linktext + "</a>")
//-->
</script> |

E-Mail Address Encoder from Automaticlabs.com

Posting your email address on a website
is a sure-fire way to get an Inbox full of unsolicited email
advertisements. The Enkoder protects email addresses by converting
them into encrypted JavaScript code, hiding them from email-harvesting
robots while revealing them to real people.
There are two versions of the Enkoder, available:
For users of all platforms, the Enkoder Form is available
online, 24 hours a day, for free. For users of Mac OS X 10.2
or newer, you may also download the Enkoder desktop application.
It has all of the same features as the Enkoder Form, but runs
locally on your very own Mac.
This tool is only useful for protecting
an email address on a web page you've designed in HTML. It
cannot be used when sending email or when posting your address
into a web form, or adding your comments to a forum.
Here are 2 examples of my E-Mail Address, which were
encoded by this web site.
Each E-Mail Address was encoded using a slightly
different method. See
site for details.

| Using
Graphic Images Instead of E-Mail Links |
Another way to stop web
spiders from harvesting your e-mail address is to simply use
graphic images instead of E-Mail links. Human eyes can read
the text, but web spiders cannot. You give up the convenience
of clickable links and force people to type the e-mail address
by hand! But since the web spiders can't read graphic images,
this method protects you from potential spammers. |

Using
Character Entities to Encode E-Mail Links
http://www.wbwip.com/wbw/emailencoder.html
This web site has a form that will allow
you to encode your e-mail address through the use of Character
Entities, transforming your ascii email address into its equivalent
decimal entity. Simply enter your regular e-mail address in
the first text box, click the encode button, and then highlight
and copy the resulting code produced in the second text box.
The encoded e-mail address can be read and
translated back into its original ascii text by almost any
web browser without any further action on your part. Just
replace all instances of your e-mail address on your pages
with the code, and you won't have to worry about spam lists.

This method, however, is not foolproof. I
found this web
site, which suggests that with just a few lines of code,
the web spiders can harvest the addresses created with the
character entities. So, using JavaScript or Graphic Images
seems to be the best bet these days. I was previously using
the character entities for my web sites, but I will now be
adopting the JavaScript approach.

Wpoison:
Trick Spammers into Harvesting Fake E-Mail!
www.monkeys.com/wpoison/ |
| Wpoison is a free tool that
can be used to help reduce the problem of bulk junk e-mail
on the Internet in general, and at sites using Wpoison in
particular. The basic idea behind Wpoison is to trap unwary
and badly engineered address harvesting web crawlers, and
to fool them into adding enormous quantities of completely
bogus e-mail addresses to the E-mail address data bases of
the spammers, thus polluting those data bases so badly that
they become essentially useless, thereby putting the spammers
who are using them out of business, or at least shutting them
down for a time and causing them some major headaches while
they try to clean up the messes in their now-heavily-polluted
e-mail address data bases. |
