A fraudster is anyone who uses deception for financial gain. In ecommerce the word covers a wide range of actors: criminals transacting on stolen payment data, operators of organized schemes like triangulation and reshipping, and otherwise ordinary customers who lie in a claim to get a refund they aren’t owed.
The Spectrum of Bad Actors
Modern commerce risk covers more than the word “fraudster” traditionally implied, which is why the broader term bad actor is often more accurate. The spectrum runs from professional criminals (stolen card operations, coordinated rings, fraud as a service operators) through semi-professional abusers (serial refund abusers, unauthorized resellers, promo farmers) to opportunists: real customers who commit friendly fraud or wardrobing once and rationalize it.
Why the Distinction Matters
Each group calls for a different response. Professionals are blocked with screening and network intelligence; they were never customers. Abusers are managed with identity-level limits and adjusted policies; some reform when the scheme stops paying. Opportunists are mostly deterred by visible verification and kept honest by good experiences. Treating all three the same either under-protects against professionals or alienates the recoverable majority.
Frequently Asked Questions
What motivates most ecommerce fraud?
Economics. Fraud concentrates where payoff is high and friction is low, which is why resalable goods, generous policies, and busy seasons attract it, and why raising the cost of abuse redirects it elsewhere.
Are most fraudsters professionals?
By loss volume, organized actors dominate payment fraud, but by headcount, opportunistic first-party abuse involves far more people. NRF research found nearly 67% of consumers admit to at least one costly return behavior.
