Spiderkiller is a C program that will generate unique pages with random email addresses that will confuse harvesting bots. Compile the app:
srv-5:~ usr4$ gcc spiderkiller.c -o spiderkiller spiderkiller.c: In function 'main': spiderkiller.c:299: warning: incompatible implicit declaration of built-in function 'strlen'
The options are simple:
srv-5:~ usr4$ ./spiderkiller -help Usage: spiderkiller [-help] [-n ] [-k ] [-r ] [-x] -help: print this message -n: set maximal number of addresses created -k: set maximal size in kilobyte of the created code -r: set the random seed (an integer). Default is the current time. -x: print no html, just a list of addresses The purpose of this program is to create lists of bogus email addresses to clobber automated address collection tools, of the kind that spammers use. Feel free to put these on your web pages; the more, the merrier. (C) 1998 Peter Selinger. This is free software under the GNU General Public License. srv-5:~ usr4$
Let’s generate a 1000 address web page:
srv-5:~ usr4$ ./spiderkiller -n 1000 > index.html srv-5:~ usr4$
Just to be polite, put this file in a directory disallowed in robots.txt:
srv-8:~ usr4$ tail -n1 robots.txt Disallow: /harvestme/ srv-8:~ usr4$
Bad bots dis robots.txt.
