that is simply not true and defeats the purpose

I disagree.  That description of DCC seems very accurate to me.  See
http://www.rhyolite.com/dcc/ and particularly statements like:

- DCC does not "list" domain names or IP addresses, but detects bulk
mail messages.

- If DCC users want to receive your bulk mail, they must whitelist it by
adding your IP address, SMTP envelope sender, RFC 2369
<http://www.ietf.org/rfc/rfc2369.txt> SMTP List-* headers, or other
characteristics of your mail to their whiteclnt files
<http://www.dcc-servers.net/dcc/dcc-tree/homedir/whiteclnt>.

Why are you saying it's not true?

because i can't find any sense in give bulk mail just because it is bulk mail - indepdendent of subscribed, double-optin and what not - a penalty

however, the real problem of all the hashing services is the way how personalized parts get stripped and what part of a message is taken for the hash (without that it can not work at all) and i saw *for sure* single mails written by a human and not a bluk mail as false positive

the other problem is how people report their mail - there are plenty of idiots which confuse the "delete" and "report as spam" option regulary
