A 2-question pre-lander dropped chargebacks from 9.4% to 3.1%.
Cohort: one rebill (trial) offer, US + CA, 11 weeks. Chargeback rate = disputed transactions ÷ approved transactions.

— Weeks 1–5, no filter: CB 9.4% ▏▏▏▏▏▏▏▏▏ (n=4,100 approvals)
— Weeks 6–11, pre-lander asking age + payment-method confirmation: CB 3.1% ▏▏▏ (n=4,650)

Approved volume fell 12% (weaker intent filtered out), but net revenue rose 19% because the network stopped clawing back commissions and lifted the cap.

Read: a 6.3-point chargeback cut bought reliability the volume loss couldn't offset — the network's trust score, not the click count, became the constraint.
