Honeypot For Identifying Email-Harvesters

Cheese Man writes "Mark Pilgrim describes a simple way to identify email-harvesters: "In each page I serve, I include a bogus email address, encoded with the date of access as well as the host IP address ... This has allowed me to trace spam back to specific hosts and/or robots." There's even a simple one-line example done with PHP. (Thanks to BoingBoing for the links.)"

Nothing new

[Rosco P. Coltrane]

Lots of people, including me, use different middle names or initials when applying for something in writing, by snail mail or by telephone. When junk mail comes back in the mailbox, it's easy to know what company sold your information to whom, or at least which company was the initial recipient of the bogus info and which was the last.

Try wpoision, it's a CGI script to generate a random set of email address, infinitely deep. Very fun.

You can do the same with a lot of addresses

[wheany]

You can often do this even without a throwaway domain. Many addresses can be tagged by adding a "+" (plus-sign) and anything between the user name and the @-sign.

For example wheany+sd@iki.fi, wheany+SpamTastesGood@iki.fi, wheany+glahglahglag@iki.fi, wheany+spammer.com_on_06_22_2003@iki.fi all go to the same mailbox.

Its called a false dichotomy

Why not?

Things are rarely polar opposites. You can't just say, "Well kid, are you a communist or for a lassiez-fair market." There's tons of middle ground.
The formal name for this is the False Dichotomy. More
Extremes only really exist as abstract concepts.

Advocating regulation or laws to protect against abuse is hardly pro-DMCA.

Giving credit where it is due...

It wasn't Mark Pilgrim that described a simple way to identify email-harvesters. The link shows it was George A. Theall in a comment on Mark Pilgrim's weblog.

How Cheese Man got mixed up is beyond me, as comment by George A. Theall is clearly displayed at the bottom of the comment.

mod_spam_die

[c_g_hills]

Another tool to throw a spanner in the works for spammers is mod_spam_die for Apache. It generates a random page with recursive links and fake addresses, thus causing the spammer's database to fill up with useless addresses. There's an example at chaz6.com/spam_die.

Let's combine some ideas here.

[The Monster]

1. Set up one or more machine names on your domain specifically for spam traps.
2. All email addresses on your page are munged thusly: When a computer at 123.45.67.89 requests a page containing the email address

   Dr. John Q. Doe <john.doe@isp.com>

   it becomes

   Dr. John Q. Doe (john DOT doe A-T isp DOT com) <16552.IP.123.45.67.89@spamtrap.domain.org >

   where the exact formula should be a bit vague, so as not to be easily defeated by bots, but obvious to humans
3. The email server for spamtrap.domain.org is Teergrube (tarpit) that locks up the spamming computer AND sends notification back to the web site to serve that IP links to a world-wide tarpit ring, so as to get the spammers as many tarpit email addresses as possible
