Auditing scrub timing exposed a network shaving 11% — switching recovered $7k/mo.
Cohort: one buyer cross-checking their own pixel fires against network-reported conversions, 60 days.

— Self-tracked conversions: 4,420
— Network-credited: 3,930, a 'scrub' of 11% ▏▏▏▏▏
— Two competing networks on mirrored traffic scrubbed 3% and 4% ▏▏

The 11% network had no scrub clause justifying the gap. Moving volume to the 3% network recovered ~$7k/mo at the same payout.

Read: undisclosed scrub is invisible without your own pixel — a same-traffic comparison turned an 11% silent haircut into a switch decision (n=3 networks, 60-day mirror).
