Survey scam

In a survey scam, the fraudster posts ads for participation in a survey regarding employee/employer relationships during the current economic crisis. Those who apply are required to send a copy of their payroll check as proof of employment. After sending the copy, the victim never hears from the fraudster again; however, the employer’s account is drained of thousands of dollars by way of fraudulent checks.
