Spam: Hiding Your Email Address

In many instances you will want to put your email address on

your website, even if you provide a form as a contact method.

This is useful because it increases the number of ways that

someone can contact you. Why is that important? Because

presumably if you have a website you are attempting to

communicate with the world - and communication goes both ways.

If you have a commercial site then the answer should be obvious

- someone may want to purchase something.



Another reason to put an email address directly on your web page

is for people to request information via autoresponder. These

allow your visitors to click a simple mailto link and get your

promotional materials or articles in their email inbox.



The problem with directly including your email addresses on your

page is spam harvesters. These a programs created by scum and

run by ignorant or unethical fools. What they do is search

through the internet, looking at web sites and pages for email

addresses to add to those million email address collections that

you see advertised (mostly in spam) all over the place.



There is really no ironclad way to prevent these bottom-feeders

from scanning your web site for email addresses. There are a

number of techniques, however, to make it a little more

difficult for them.



One of these is to code your email addresses in something called

Unicode. This is a "language" for encoding special characters on

web pages. All modern browsers support Unicode as it's primary

intention is to allow languages all over the planet to be

represented.



For example, the following email address:



webmaster@internet-tips.net



will be shown in Unicode as:



webmaster

@internet

-tips.net



As you can see from the table below, using Unicode characters is

simple. Just substitute the Unicode sequence in the table for

the corresponding character. Then use all of those sequences

wherever you want to put that email address.

a a i i q q y y D D L L T T b

b j j r r z z



I suppose it is inevitable that the scum spammers will

eventually make their spam robots smart enough to understand

these codes. Until then, however, it is a reasonably effective

technique for reducing spam in your inbox.
