Yes, exactly, social risk, not marketing. And it's measurable in my data: the league that's 70% full converts way better than the identical league sitting at 20%, same copy, same price. "Almost full" is doing the peer-proof work that no feature line can. What's been most interesting is that the strongest signal isn't even my messaging, it's getting current players to post "I do this, come join," because that's the unfakeable version of "someone like you is already here." Curious in your B2B cases, what actually generated the peer proof, customer logos, case studies, or something more peer-to-peer like a user community or referrals?
