"Vipul's Razor is an open source (see resources)
project hosted by SourceForge. Razor is a "distributed and
constantly updating catalog of spam in propagation." Think of it as
a real-time Dewey Decimal System of spam, but it does more than
just index spam. It tracks, identifies, and harasses spam, and when
it finds spam, it destroys it.
Unlike many open source projects, the installation of Razor was
not in any way circuitous. Vipul Ved Prakash even had the audacity
to include a well-packaged tarball of required Perl modules along
with a global makefile. What is this guy thinking? Does he not know
that all of us open source people enjoy being placed on the
medieval rack when we install software?"
