I was once approached by someone representing (or at least claiming to) the Nature Conservancy. They had a worthy-sounding pitch but I told them that as a rule I didn't donate on knee-jerk reactions, but that I would be happy take down their info, have a closer look, and consider a donation. They guy said, "oh like on Charity Navigator", whipped out their phone and showed me near-perfect scores for them on Charity Navigator. I stuck to my rule, got home, and looked them up. At the time they had 2/4 stars on Charity Navigator. Guy was using an old screenshot or something.
