Q: I'm getting paid for conversions I don't think I drove. Should I worry?

A: Yes — quietly. If a traffic source is stuffing your click logs, you may be receiving conversions stolen from other channels through click flooding (firing huge volumes of low-quality clicks so the last one wins last-click attribution). When the advertiser audits, the clawback lands on you.

The tells you're missing:

— Your click-to-install or click-to-conversion time is implausibly short OR suspiciously long-tail, suggesting clicks were sprayed to catch organic conversions.
— One sub-source sends enormous click volume with a near-zero conversion rate, then suddenly 'converts' on big actions.
— Your conversions cluster right after app-store or organic spikes you didn't cause.

Fix: segment by sub-source and look at the click-to-conversion time distribution. Healthy traffic has a sane curve; flooding shows a spike at the very short end. Cut the sub-source before the advertiser does it for you and reverses your payouts.

Short version: free conversions can be hijacked attribution. Watch click-to-conversion timing per sub-source.
