YC isn't that unknown and you can absolutely judge that org for funding stuff like this, you really don't need that much detail. And if you have interacted with a lot of the "founders" you know that statistically you're in the clear to judge them all too. It's a pretty weird world where a lot of dumb exists, like A LOT. The realities of their lives are frankly immaterial anyway, it's about the output (and input in case of VC money).
