Unfortunately, 'wrong' is not equivalent to 'untrue'.

Question: Do you have the same problem with DCC?
(http://www.rhyolite.com/anti-spam/dcc/)

False positives are due to honest mistakes (fat-fingered the report
key), ignorance (automated reporting and spamtraps), and malice. The
question is, where do your particular false positives come from? That's
a rhetorical question because only someone privy to the innards of the
Razor database can know that.

Honest mistakes? Those people that are paying attention when reporting
know how to self-revoke and they do to preserve their TeS.

Ignorance? I blame automated reporting and spamtraps. I don't know how
the EFF newsletter is managed, but if it doesn't confirm subscriptions
and periodically reconfirm users (BUGTRAQ does it at least annually),
it's liable to end up in a poorly-configured spamtrap somewhere. So the
first step you can take is to ensure your (re)confirmation and scheme is
working.

Malice? Aside from the Attorney General and a handful of
sexually-inactive teens, I can't fathom who'd bother, but for the sake
of argument, let's assume there's a He-Man EFF-Hater's Club (HEC) out
there somewhere. If the HEC only reports your newsletter as spam and
someone else revokes HEC's report, HEC's trust level drops. The damage
is done initially but HEC's capacity to damage is limited with every
bogus report they file. They can resubscribe as HEC2, HEC3, etc. to
clear their reputation and the cycle can continue but it's pretty clear
you'd need a decicated and large conspiracy to do this, the probability
of which is small but non-zero. Also, it's doubtful that most of the
conspirator(s) are manually reporting your newsletter so you may be able
to shed them by periodically reconfirming subscriptions (above) if you
don't already.

We're assuming that Razor's trust model is reasonable which may be the
crux of your argument. I'm not happy that it's not made public but I
understand the rationale for keeping it hidden for the time being and I
respect that decision.

But assuming that, flawed or not, the trust model is not going to change
anytime soon, there are things you can do to mitigate the damage done by
bad reports. For example, break each newsletter mailing into several
smaller mailings. After each burst goes out, wait a bit and check your
message against Razor; if it's listed, revoke the listing and send the
next burst. Repeat until the whole mailing goes out. If you're really
paranoid (and who isn't these days?), intelligently shuffle the
recipients to home in on potential reporters. Extremely paranoid people
would send widely different content to different groups of recipients to
further zero in on malicious reporters, all without cooperation from the
maintainers of the Razor database.

Another route is working with the Razor developers/Cloudmark to improve
their trust model. I'm sure the EFF has knows people who are smart,
pleasant, and feel strongly about promulgating good anonymous trust
systems. Or arranging a smoky backroom deal with the db maintainers to
keep your newsletter out of their database. This might not be the best
list for discussing either of these.

Yes, it's extra work and I expect some or all of these suggestions will
offend the EFF's sensibilities, but you asked for answers, not
solutions[1].
