Free-trial abuse¶
Definition¶
Free-trial abuse is the fraud class where a single actor repeatedly cycles through the same product's free trial — by creating new accounts, varying email aliases, swapping payment methods, or otherwise bypassing the platform's one-trial-per-customer constraint.
Sibling to concepts/multi-account-abuse (which is broader — multiple accounts for any extraction motive, including stolen- card spreading) and concepts/pay-as-you-go-abuse (which is post-tier-graduation: usage-based-pricing exploitation rather than free-tier).
Why this matters in the LLM era¶
Free-tier credits at LLM platforms have direct dollar value (unlike, say, a free-tier SaaS app where the value is largely informational). A free-tier voice / image / chat account at an LLM platform can be worth $5–$50 in compute. Industrial-scale abuse of free trials becomes an extraction vector.
The 2026-05-27 Stripe Radar post references an earlier dedicated post — "Last month, we shared how Radar addresses one of these fraud vectors with free trial abuse prevention" — and treats free-trial abuse as a member of the broader agentic-era abuse-vector taxonomy that includes concepts/multi-account-abuse and concepts/pay-as-you-go-abuse.
Detection¶
The detection mechanism is described in the cited prior post rather than in the 2026-05-27 disclosure; Radar's free-trial abuse prevention is positioned as a complement to multi-account- abuse detection on the same sign-up surface.
