Most teams look for bonus abuse after the campaign goes live.

By then, the damage is already priced in.

Fake accounts, bots, and referral farms do not wait for launch day.
They wait for the moment eligibility rules are announced.
Then they prepare devices, identities, and referral paths in advance.

So the real question is not "how do we catch abuse once it appears."

It is "what do we check before the first signup bonus, referral reward, promo code, coupon, or free credit ever goes out."

That means reviewing device intelligence, bot detection, VPN and proxy signals, behavioral biometrics, and link analysis as part of campaign planning, not as a cleanup step afterward.

CrossClassify helps growth and fraud teams put these checks in place before launch, so promo codes, loyalty points, and welcome bonuses scale without quietly funding fake accounts and fraud rings.

I put together a bonus abuse best practice checklist covering what to plan before a campaign launches.
