That just means you aren't sending what you'd consider to be spam.

If a statistically valid sample of an ISP's users (as processed by their own
user reputation systems) think something is spam, why would that ISP
disagree?

I know it's a big shift in thinking from the classic anti-spammer attitude,
particularly the pornography test (I know it when I see it.)  But, it's a
shift that all of the big ISPs have already made: they'll listen to their
users before they'll listen to random external parties.
