I saw an interesting link suggested in this group for the spam problem:
http://www.e-scrub.com/wpoison/
From there I saw this program.
http://www.e-scrub.com/cgi-bin/deadbolt.cgi/show_demo_entry
These are both interesting programs, but may have inherent problems.
wpoison: Traps e-mail web crawlers, but what is to stop it from trapping
other web crawlers that altavista, webcrawler, excite, yahoo and
other people use?
It boasts that it can provide an almost infinite number of bogus
e-mail addresses as well as hyperlinks. (these hyperlinks point
directly back to the same page) Why would you want to trap a web
crawler on your site, using your bandwidth and resources almost
indefinitely?
Deadbolt(tm): This filters out known e-mail spammers, from an automatically
update-able lists, provided by E-scrub Technologies. What
happens when a majority of ISPs are using a filter like this and a
legitimate e-mail address is accidently put in the list?
That e-mail address would then be denied by a majority of the
ISPs.
