Spam Fighter Script

Thousands of small business webmasters briefly lose their domain names at expiration, due to a simple lack of understanding about the roles of three key players in the drama: domain name registrars, web hosts and internet service providers. Fortunately for most, they learn quickly how to save their web site from oblivion by using the 30 day redemption period for expired domain names enforced by ICANN. One simple solution is to extend domain registration for the maximum ten years. The other solution is to treat domain registrar data as the critical business element it is.

I Can't Remember Where I Purchased My Domain Name!

It wasn't until my third client had called asking how to regain control of her domain name that I realized that it was a common problem for small business webmasters to forget where they had registered their domains. WHOIS my registrar? Why didn't I get an email about renewal? Why did my site stop working today?

People rarely realize how important it is to keep their domain registrar notified of changes to their email address and and other contact information. The registrar will send renewal notifications to the email address last on file. For most domain owners, the only time they think about contacting a registrar is the day they reserve their domain name. If they move to a new city and get a new internet service provider, it doesn't occur to them that the old email address will change and that meeans that the registrar can no longer contact them through the previous address, or phone or fax as each of them change and we rarely notify the controller of our domain of those changes.

Sometimes the first indication a business owner will have that there is a problem is the day their web site stops working. If they failed to notify their domain registrar of changed email address, they may never have received their domain renewal notice. Since many registrars honor a 30 day "redemption period" allowing expired domains to be redeemed, it may be possible to save the registration within 30 days following expiration by contacting registrars during 30 day domain redemption periods.

A common way for spammers to create their vast lists of email addresses is to cull web pages for "mailto:" tags. There are many different programs, available for small to huge costs, which will do this automatically, easily and efficiently.

I monitor my web site log files on a regular basis, and I'm always amazed at the vast numbers of spam harvesting programs that regularly scan my pages. Not only do these obnoxious things steal email addresses, they use bandwidth which I pay for without any kind of compensation. I put up my web pages for people to read not for some scumbag spammer to scan them.

There are many ways to combat the spammer. None of these methods are perfect. As in any war, both sides are continually developing new weapons to use against the other. New methods work for a short time until the enemy comes up with countermeasures and overcomes the weapon.

One of the more effective ways to confuse the spammer (not hard because they don't tend to be very bright) is the "poison pill" defense. This consists of handing the spam harvesting robots some pages which appear juicy, full of yummy email addresses ripe for the picking.

The email address on these pages are fake. They have nothing to do with reality and exist only to choke the spam robots, causing them to overflow and possibly even crash.

Here's how a typical poison pill works. A script is created which performs all of these tasks. It is important that the scripting be done on the server, so CGI, ASP, PHP or a similar scripting language must be used. Server side scripting must be used because many spam robots are not smart enough to understand client-side scripting languages such as JavaScript.

The script creates a page which appears in all ways to be a normal document in a web site. The page may include some text informing human visitors of the intention (this is important so any people who see the page are not confused).

It also needs to include a meta tag informing all robots not to index the page. This is critical, as you do not want robots such as googlebot or scooter (the spiders for Google and Altavista, respectively) seeing this stuff. Don't worry, spam harvesters ignore these meta tags.

The script gives the page a name, usually randomly picked from a database or made up somehow, and fills it with a few dozen (at the most) email addresses. These email addresses are cleverly created to appear perfectly valid but actually are useless - they are just made up.

Links to other fake pages are created for the spam harvester to follow. Any robot (or human being, for that matter) that follow these links will find similar pages, full of desirable email addresses.

Depending upon the robot, it's possible the spammer could gather tens of thousands of totally fake, unusable email addresses before his robot blows itself out of the water. It's even better if the robot survives, as the spammer now wastes his time sending messages to nonexistent email addresses.

In the meantime, the harvester has been lured away from valid pages which may or may not contain email addresses.

My site, Internet Tips and Secrets, uses one of these poison pills. It is called wpoison and it really works well. If you want to see it, look at this page.

This is just another weapon in the war against spam.

Is it effective?

I know from personal experience that it does trap spam robots, and it does seem to lure them away from real, useful email addresses.

Is it ethical?

I believe so, as long as you are careful to include the meta tags to inform "good" robots to leave the pages alone as well as some text to let your visitors know what's going on.

It's not as satisfying as spamcop.net, and there is no where near that pleasant glow of success upon learning that some scum spammer has had his ISP cancel his account, but the poison pill is useful nonetheless. My advice is to include it in your arsenal along with the other weapons and tools at your disposal.
