How do bots exploit sportsbook promos?

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.
