For years I didn’t worry much about spam.
But lately it’s got out of control. Over half of my email
is now spam, and it was growing by the week – until I took
action.
This article shows you some strategies for winning the war
on spam.

How Do They Get Your Address?
————————————————
In the old days, spammers got their addresses mainly from
Newsgroups – if you didn’t post to Newsgroups, you were
reasonably safe. But they’re now using a much more
efficient method to build their lists – email harvesters.
Email harvesters are robots that roam the Internet
collecting email addresses from web pages. Examples are
EmailSiphon, Cherry Picker, Web Weasel, Web Bandit and
Email Wolf, to name just a few.
How can you protect yourself from email harvesters?
By ‘munging’ (mung = ‘mash until no good’) or cloaking your
email address.
There are many ways of munging your address – the easiest
technique is to use ASCII code for the punctuation in your
email address (instead of symbols).
For the colon after mailto use : and for the @ symbol
use @ and for the period use . . With this method,
your email address would become:
mailto:yourname@yourdomain.com
but it will display as:
mailto:yourname@yourdomain.com
Your email address will appear exactly as it did before,
and it will still be ‘clickable’, but email harvesters will
ignore it and move on.
There are also JavaScript’s that you can insert into your
web page that will make your email address visible to
humans but invisible to harvesting programs. Here’s one
that works very well:

How To Fight Spam
—————————–
The most important thing is never, ever, reply to spam.
Most spam contains an innocent-looking ‘remove me’ email
address. Do not use it. Here’s why:
Spammers typically buy a CD containing a million or so
email addresses, but they have no idea how many of those
addresses are active. So before beginning their marketing
campaign in earnest, they send out a ‘test message’ to the
entire list.
The test message contains an email address for removing
yourself. When you reply to that address, it confirms to
the spammer that your address is active and therefore worth
spamming.
Worse still, the spammer may be distilling from that CD a
list of confirmed active addresses that he will then sell
to another spammer.
The key to dealing with spam is to report it to a 3rd
party: (1) the affiliate program that the spammer is
advertising, (2) the spammer’s web host, or (3) the ISP the
spammer used to connect to the Internet.
When you report spam to a 3rd party, remember to be polite
– they didn’t send the spam and they’re probably just as
anti-spam as you are.
(1) Reporting to Affiliate Programs
Many spammers are affiliates advertising someone else’s
products or services. So look for a website address that
contains an affiliate link, something like this:
www.affiliateprogramdomain/841526
Then just send an email to the affiliate program
(abuse@affiliateprogramdomain.com), informing them that you
are receiving spam from one of their affiliates.
Most affiliate programs have zero tolerance for spamming
and will remove an affiliate spammer without warning.
Now, affiliate spammers don’t want you to see their
affiliate link, so many of them send their email as HTML.
All you see in the message are the words ‘Click Here and
Order Now’.
But in your browser just click on ‘View Source Code’ and
search for the letters ‘http’. That will take you to the
spammer’s affiliate link.
(2) Reporting to Web Hosts
If the spam doesn’t contain an affiliate link, it’s likely
that it is coming from the owner of the domain name. In
that case you’ll have to report it to the spammer’s web
host or their ISP.
To make a report to the spammer’s web host just go to
Whois, the directory of registered domain names:
http://www.netsol.com/cgi-bin/whois/whois
Type in the spammer’s domain (the website address that
appears in the spam) together with the extension (.com,
.org, .net etc).
The host for that domain will usually be listed as the
Technical Contact in the Whois record and there will be an
email address for contacting them.
(3) Reporting to ISPs
To report a spammer to his Internet Service Provider,
you’ll have to look at the spam’s ‘extended headers’.
Extended headers show the servers that the message passed
through in order to get to you. The instructions for
viewing extended headers will vary depending on what email
client you are using.
=> In Pegasus Mail, open the offending message and then
right-click and choose ‘Show raw message data’.
=> In Eudora Light, click on ‘Tools’ in the top menu
bar, and then ‘Options’, and then select the
checkbox option that says ‘Show all headers (even
the ugly ones)’ and click OK.
=> In Outlook Express, open the offending message,
select ‘Properties’ from the File menu and then
click the ‘Details’ tab.
Reading and understanding extended headers is quite a
detailed subject. Here’s an excellent free tutorial on how
to decipher extended headers:

As an alternative to these reporting techniques, you could
use a web-based spam reporting service such as SpamCop
(www.spamcop.net). SpamCop deciphers the spam’s message
headers and traces the mail back to its source.
Wishing you every success in the fight against spam!
