Social Signal & Information Integrity / Reputation and Trust Systems
SUB-T03-028Fraud and Abuse Signals
Definition
Fraud and Abuse Signals examines combining behavioural and transactional indicators to identify fraud or abuse without excessive false positives within the broader domain of the design, use, fairness, portability, attack resistance and recovery mechanisms of reputation and trust systems.
Why this matters
Fraud and Abuse Signals can materially affect autonomy, safety, public trust, market integrity, community cohesion and institutional decisions. Poorly designed interventions can suppress legitimate speech, entrench bias or create false confidence.
Research questions
Under which conditions can combining behavioural and transactional indicators to identify fraud or abuse without excessive false positives be measured or improved reliably, and how do effects vary by platform, population, context and intervention?
Hypotheses
A transparent, context-aware approach combining provenance, behavioural evidence and accountable human review will improve fraud detection and legitimate-user protection more than single-score, content-only or opaque automated approaches.
Proposed methods
algorithmic audit; fairness testing; adversarial attack simulation; user studies; longitudinal reputation analysis; governance review; portability experiments; expert review; affected-user interviews; reproducibility testing; methods adapted specifically to Fraud and Abuse Signals
