Respondent + response
Respondent Fraud Detection - and the Answers They Submit
Respondent fraud is the classic problem: is this person real, unique, and in market? That is table stakes. Maxna treats respondent fraud as half the job. The other half is response fraud - AI text and empty answers from otherwise “valid” people.
Why Maxna is different
Other platforms score the respondent. Maxna scores the respondent and the response.
Device IDs, bots, VPNs, and duplicates are necessary. They are not enough. A real device can still paste ChatGPT into every open-end. Maxna's proprietary AI grades what people type - so sample integrity is both who they are and what they say.
Respondent quality
Where most tools stop
- Device fingerprinting and environment risk
- Bots, scripts, and click farms
- VPN / proxy and geo mismatch
- Duplicates and professional respondents
Response quality
Maxna's proprietary AI layer
- AI-written and synthetic open-ends
- Low-effort and copy-paste answers
- Cross-question consistency
- Open-end scoring before the complete is paid

Definition
What respondent + response means in practice
Respondent fraud detection covers bots, farms, multi-ID duplicates, professional takers, and spoofed environments. Competitor stacks often stop there. Maxna runs those checks and then scores the content, because a cleared respondent can still submit synthetic research.
Why it matters
What breaks if you skip this layer
Respondent-only is an incomplete product
Identity vendors can pass a clean device that immediately pastes an LLM into every verbatim.
Farms evolved
Organized labor now uses real phones and residential proxies. You need behavior and content, not only IP.
Pros look like good panelists
High-frequency takers survive attention checks. Linking and behavioral patterns catch what trap questions miss.
Signals
What Maxna looks at
Respondent quality first. Response quality with proprietary AI whenever the threat lives in the answers.
Identity & environment
Device graph, IP reputation, VPN/proxy, geo/locale mismatch.
Uniqueness
Duplicates within a study and across suppliers when linking is on.
Human vs automated
Headless, replay, and farm cadence.
Then the answers
Proprietary AI on open-ends so a “real” respondent cannot ship fake research.
Implementation
How teams deploy this
Screen the person first
Outer shell and behavior decide if the session should continue.
Score the response
Open-end and consistency models decide if the complete is usable.
One reject taxonomy
Ops sees whether the fail was respondent-side or response-side.
Platform-specific walkthroughs live in integrations. Tiers are on pricing.
Limitations
False positives and honest boundaries
Integrity software that cannot admit uncertainty is not trustworthy.
Legitimate privacy tools exist
Some real respondents use VPNs. Network risk is a signal, not an automatic ban - combined with behavior and content.
FAQ
Questions buyers actually ask
Is respondent fraud the same as sample quality?
Respondent fraud is who they are. Sample quality also includes what they say. Maxna covers both.
Do I still need a fingerprint vendor if I use Maxna?
Maxna already includes device and network intelligence as part of respondent quality. You do not need a second identity-only product to cover that layer.
