That’s user-submitted data. The PCH directory is twenty years old, and is independently verified by our staff. So what’s there isn’t always up-to-date, but we do differentiate between rumor and something that’s been verified by someone going and laying eyes on it.
It is ever-so-slightly better than user-submitted data. Specifically, if an IX or a colo tells us "this person says they are a [Customer|Member|whatever] and they are not", we will remove that row from the DB. Then again, PeeringDB never claimed to be anything but user-submitted data. Just the opposite.

Taking just Seattle IX (since I have a personal interest there :), it says "177" under "participants", but <http://www.seattleix.net/participants.htm> disagrees. To be clear, PCH does a better job than most (all?) others. And a ridiculously difficult job it is. Finding how each IXP presents its user / traffic / whatever data an trying to collate it is nearly impossible. But thank you for trying! -- TTFN, patrick
