    Hello,

    After launching a survey on MTurk that links out to Qualtric software (with workers entering a completion code back into MTurk for payment), I noticed an issue with lots of clearly duplicate responses of workers taking the survey multiple times and submitting for payment. Since I have it set on MTurk to only allow unique workers to respond, they must have multiple MTurk accounts from which they are taking the survey and getting paid. This is seriously affecting the validity of my data. Anybody else encounter this before and have a solution?

    Thanks!

    This is a known issue that can occur when participants create multiple MTurk accounts or share the completion code, bypassing your MTurk restriction on unique workers. In Qualtrics, enable IP address tracking (while staying compliant with privacy policies). While IP addresses aren't perfect due to VPNs or shared networks, they can still help flag suspicious duplicates.
