Quick Answer
Round-number transaction spikes often look unnatural because genuine customer purchasing usually has more price variation. Stripe may read these clusters as testing, scripted behavior, or artificial order patterns.
What Stripe Is Likely Comparing
- transaction amount distribution before and after the spike
- source and device mix for round-number purchases
- fraud, dispute, and approval quality for that cluster
Most Common Root Causes
- bot-driven test transactions
- one campaign or product generating artificial order structure
- abusive incentive or affiliate patterns
Evidence Stripe Will Weight Most
- amount-distribution analysis
- cohort-level source and device data
- controls that reduced the abnormal concentration
Operational Fix Sequence
- Isolate the source of round-number concentration.
- Check for attack or incentive abuse.
- Tighten controls on the abnormal cohort.
