Multiple individuals transacting on the same account is a red flag for which phenomenon?

• A. Front Companies
• B. Smurfing
• C. Stacking
• D. Integration

Answer: (B)

Smurfing is the practice of moving funds through many small transactions or using multiple people to carry out activity in order to stay under reporting thresholds and obscure ownership. When you observe several different individuals performing transactions on the same account, it signals that the true owner or source of the funds is being masked by pooling activity from various participants. This pattern is a red flag because it fits how smurfing aims to avoid detection and to create confusion about who owns and controls the money.

For context, front companies involve using a fake or shell business to route funds; stacking and other layering ideas refer to different ways funds are dispersed across accounts or steps in a laundering sequence, whereas integration is about funds appearing legitimate after laundering. The described behavior aligns most closely with smurfing.
