A global rate limit at the edge is not enough. The signup-bonus endpoint, the referral endpoint, the promo-redemption endpoint each need their own limits. Identity signals beyond email. Device fingerprints, payment-method fingerprints, phone number verification, and KYC verification all carry more signal than email addresses, which are cheap to create in bulk. Audit trails on value-dispensing operations. Every issued credit, applied promo, or granted bonus should be logged with the triggering user, target user, IP, and timestamp. When abuse is suspected, the log is how you untangle it. Maximums at every layer. A per-action cap (e.g., one bonus per account) plus a per-account cap (e.g., total lifetime promo value) plus a per-source cap (e.g., per payment method or per device) gives defense in depth. Asymmetric consequences. Actions that give value should be harder than actions that don't. Making someone wait 30 seconds, or complete a CAPTCHA, to claim a reward is fine. The legitimate user clicks once and moves on; the automated abuser suffers a per-request cost.\n\nAttribution: Adapted from OWASP Cheat Sheet Series under CC-BY-SA-4.0.
