I find it a bit too hand-wavy. It would take me about 30 minutes to produce
a script to automate C/R..but I would have to use a valid email
address...and there are additional ways to thwart the process as serach
engines use for URL submission..if you don't know what I'm talking
about..submit your site to Lycos or AltaVista

... As I mentioned before, we need to better define the goals of
C/R. Is is to make sure that senders are legit, or is it going
to an extra
level to making sure the sender is human (essentially creating a Turing
Test). As for having spammers set up automatic responders, see TDMA FAQ,
section 1.1 (http://tmda.net/faq.cgi?req=all):

"1.1. Can't spammers just setup an auto-responder to defeat TMDA? *
In theory yes, but in practice this is not likely to happen.
Most SPAM is
unrepliable, so TMDA's confirmation requests are never
delivered to them.
They use non-valid return addresses as to not incur the cost of the
tremendous number of bounces they generate. Using a valid
return address to
process all the bounces looking for confirmation messages to
auto-reply to
would defeat their economies of scale. It would also make them easy to
block, track down and report, sue, etc. In short, trying to
thwart TMDA in
this manner would defeat the cost-effectiveness of the bulk-mailing
process. Simple economics keep us safe.
This para. is interesting. It proposes some significant
properties of SPAM.
Is this information verifiable? Was a study done to determine
it's validity
empirically, or is it anecdotal? It does, at first glance,
appear valid but I
would be interested in validating the study used to garner this
information
before preceding on its base arguments. Are there references in
the document?
