Don’t simply ask “Do you actively work to prevent survey fraud?”
Any data collection vendor will say yes to that.
Instead, ask about specifics — “What specific fraud prevention steps do you take?” Listen to how specific they get.
- Named fraud prevention platforms
- How they block bots and AI agents
- Duplicate device/IP detection
- Screener review and revision
- In-survey quality controls
- Diversifying sources through Sample aggregation
If the answer is vague citing things like “industry-standard practices” or “proprietary methods” – there’s your red flag.
Quality vendors will walk you through their entire fraud prevention stack without hesitation. Because they actually have one.
Are you vetting your sample vendors like this?
