**Short answer:** Promo abuse bots mass-create accounts to harvest sign-up offers, free bets, and referral bonuses, then extract the value through matched betting across accounts. The promotion designed to acquire one customer funds a fleet of synthetic ones - and your acquisition metrics read the spend as growth.

## The extraction mechanics

A free bet becomes cash by betting both sides of a market through two controlled accounts. Deposit matches get churned through low-margin markets until withdrawal rules clear. Every step is automated, and every step looks like ordinary play in isolation.

## Why promo teams and fraud teams disagree

Marketing sees sign-ups spike and claims success. Fraud sees bonus cost per retained customer explode. Both are right: the promotion worked perfectly - for the farm. The gap between the two dashboards is the bot share.

## Measuring the leak

Score registrations and first-session behavior before the bonus pays out. Synthetic fleets share device, timing, and funding patterns that real new customers do not. A promo-period audit quantifies exactly what the farm took, which is the only number that fixes the next campaign.
