As a counterpoint, I run a public DNSBL and I agree with the choice of
wording used in the BCP draft. Watching the history of blacklists over
the years, few things have caused more angst and accusations than
requiring a delisting fee. Even SORBS has stopped requiring such a
fee.
I never heard of the TRBLSPAM so it is very like to be not widely known. As
a consequence there will not be many users and not many removal requests.
I used to run the MAPS RBL and now I run the Spamcop BL. Perhaps you've heard
of those?
Neither the Spamcop BL nor the MAPS RBL have ever charged for delisting. I
would never support a charge for delisting because it leaves the list open to
the accusation of false listings in order to generate revenue. SCBL currently
allows delisting on demand for a first listing and then an increasing
interval before successive self-delistings are permitted. (All listing still
expire after 24 hours with no new spam, but one can not request delisting if
an IP is delisted on demand and then relisted). To be perfectly honest, I was
really nervous about this when we implemented it, and we were prepared to
revert the change if it hurt our efficacy or accuracy. It hasn't. It also
decreased our support burden significantly.
Also, the CBL uses a similar model (although theirs was first) and is one of
the most accurate and useful blocklists in the world.
Based on my experience, I strongly disagree that pay-for-delisting is ever
necessary.
In response to the implication that it is necessary to charge a
penalty fee in some cases being an "important point not often seen by
those who never have run a public DNSBL" I would like to add my
agreement to Kelly's comments above. I created and ran the MAPS RSS,
the VISI.com RSL, and have been involved in numerous other public
DNSBLs, and I think, in 2011, that charging a fee for delisting is far
from a best practice.
