will find answers to almost all your questions here. Licence: ------------------ This is a free program. It was released to the public domain for the sole purpose of fighting spam. Copy and circulate this script to as many servers as you can. Do not remove the documentation if you give it away! Perl programmers may want to change this script according to their needs but you should not add any non-random content to the script's html output! Intelligent spiders could use it to recognize the page as a killspam page. Many thanks to the guys at escrub for the original idea (www.escrub.com/wpoison). Don't dare selling this script. Spambuster@ is watching you. If you want to do me a favor, take further actions against unsolicited emails, such as visiting (maybe even joining) http://www.cauce.org/ Disclaimer: ------------------ I'm not going to repeat the boring NO WARRANTY stuff from standard PD software licences. It applies to killspam, though. Spambuster@ is not responsible for any damages that might be caused by this program. Use at your own risk. So in case your server explodes, you have been warned :) Program purpose: ------------------ killspam generates a totally random page which feeds bogus email addresses to spiders that collect email addresses from web sites. This page consists of: - a META exclusion tag for well behaved robots and spiders - a random (funny!) headline of 3-5 random words - 2-6 random sentences of 2-12 words each. Each sentence contains one random (bogus) email address. - Another 2-6 random sentences with no links at all. - Another 2-6 random sentences of 2-12 words each. Each of these contains one random hyperlink. All links point back to this program. How does it work? ------------------ Once in a while unsolicited "spiders" (aka robots or crawlers) will travel your web site and follow all links on all pages. If a page contains an email address, the spiders add it to their database, thereby making this user part of a huge email address collection. These collections will then be sold and/or used for sending unsolicited spam emails. This is where killspam steps in. It generates pages with bogus email addresses (mostly .com and .net, but all others, too). Lots of bogus addresses will render email collections useless. Also, most spammers use "relay" email servers. These servers allow anonymous users to send emails. With lots of bogus addresses webmasters of relay email servers will receive lots of bounces which will encourage them to switch relaying off. No relaying, no spam. killspam outputs 2-6 links back to itself which means that each time a spider reads the page it will add another 2-6 links to killspam to its URL database. That way it will waste quite some time at your web site just for the purpose of grabbing lots of junk email addresses. Installation: ------------------ You may need to edit the very first line of this script to point to your server's perl executable. On any decent server #!/usr/local/bin/perl or #!/usr/bin/perl should be ok. No further customization required. Just ASCII-upload to your cgi directory and chmod 755. Please rename the script before you install it. Its no problem for a bad spider to find the word "spam" in a name. Some servers will need a .cgi or .pl extension in order for killspam to execute. Try without extension first. The random links will look much better :) Bad spiders won't find this page unless there is a link to killspam on one of your publicly accessible pages. This link could be open to the public like this (assuming you renamed killspam to welcome): Click here if you want to see a funny page You could also use a non-public link (like an invisible or transparent 1x1 pixel gif):
Don't put the killspam link to a page which cannot be reached
via your site's home page. The spider's won't find it!
Test it offline:
------------------
You can add a file name as a parameter to to the script call.
The html output will then be printed to this file. Load it
into your favorite browwser to see the resulting random page.
Limitation:
------------------
Theoretically, a spider could travel your web site for ever.
In order to protect your server from being overloaded by an
infinite number of cgi requests killspam limits the number
of consecutive pages with http links to 5. All subsequent
killspam executions will output email addresses only.
The spider will therefore add 5 times 2-6 links to killspam
to its database (=7776 executions at most). So it could
(theoretically) grab up to 7776*6=46656 bogus addresses.
Don't put the killspam link on more than 1 page, a stupid
spider might generate 7776 hits for *each* link.
Logging:
------------------
killspam will create a file killspam.log in the current
directory (your cgi-bin directory) and log all accesses
with date, time and the spider's name and IP number.
Take a look at this file if you want to find out whether
a misbehaved spider executed killspam many times.
Make sure the script has write access to the directory
it lives in.
Robot exclusion:
------------------
killspam generates the following meta tag which will
prevent well-behaved search engine spiders from indexing
the page and from following the links:
This may not work for all "good" spiders out there so you
should also add a robots.txt file to your virtual root
directory. Example:
User-agent: *
Disallow: /cgi-bin/
Disallow: /secret/
All well-behaved spider will read the robots file
http://your.domain.com/robots.txt and ignore all files in
directories "cgi-bin" and "secret". Make sure killspam
is located in one of the disallowed directories.
Ethical
considerations:
------------------
Yes, bogus email addresses will cause additional spam traffic.
I believe that this is a reasonable price for fighting spam.
The more postmasters turn relaying off, the more difficult
it gets for spammers to find a spam email server. And selling
email databases will get more difficult, too. No-one will
spend money for an email database with lots of fake addresses.
Enjoy fighting spam!
