Incentivised surveys attract both genuine respondents and fraudsters seeking easy rewards. The protection of data integrity requires a balanced approach: to make it difficult for dishonest participants to succeed without penalising honest users. In-survey quality checks are a key part of a broader fraud-prevention strategy. Surveys without such checks become fraud magnets, allowing inattentive or deceitful respondents to claim worthy incentives.

In a random sample of 61 surveys submitted to Toluna in August 2025, 64% lacked any quality checks, highlighting a gap in industry practices and the need for greater education on fraud prevention.

This article presents three core principles for designing surveys that are both fraud-resistant and user-friendly.
