Why we are strict about duplicate accounts

Identity checks and one-account rules are the least popular part of any research panel. They feel like suspicion aimed at people who have done nothing wrong. The reasoning is worth setting out, because it is not really about catching individuals.

Follow the money

A client commissions a study with a fixed budget for a fixed number of participants. That budget is what members are paid from. It does not grow if more people take part — it is simply divided differently.

So when one person runs six accounts and takes six slots in a study, they have not created value. They have taken five slots from other members, and handed the client six responses that are really one person's opinion repeated. Both halves of the transaction get worse: members earn less, and the client's findings are quietly wrong.

If that goes unchecked, clients notice their research is not predicting real behaviour, and they commission fewer studies. The pool everyone is paid from shrinks. Fraud controls exist to protect the size of that pool.

What we actually look at

Nothing exotic, and nothing that requires reading anyone's messages:

  • Impossible timing. A fifteen-minute task completed in ninety seconds, repeatedly.
  • Repeated text. The same phrasing appearing across accounts, or across studies.
  • Device and network signals. Several accounts consistently sharing a fingerprint.
  • Location inconsistency. A profile saying one country and traffic saying another.
  • Payout collisions. Multiple accounts withdrawing to one payment account.

Signals are not verdicts

Each of these has an innocent explanation. Households share networks. Couples share a laptop. People travel. Two members can independently reach the same conclusion in similar words, especially when a product has one obvious flaw.

That is why no account is closed by an automated signal. Signals decide what a person looks at; a person decides what happens. When we get in touch, the message says what the concern is, and there is a reply address — a review that cannot be argued with is not a review.

The identity check

Before a first payout we confirm you are one person with one account. It is a one-time step handled by a specialist provider, and we ask for the minimum that establishes the point. Documents are retained for the period set out in the Privacy Policy and not longer.

It sits before the first payout rather than at registration deliberately: signing up costs you nothing, so there is no reason to demand identity documents from someone who may never take a study. By the time money is moving, the check has a purpose.

VPNs

The most common reason honest members get flagged. If you run a VPN by default for privacy — a perfectly sensible habit — turn it off while taking part. Studies are sold on geography, and a German study filled by someone appearing to be in Germany while physically elsewhere is a defect in the data, regardless of intent.

We would rather explain this clearly than penalise people for a privacy habit they had every reason to adopt.

What happens to confirmed fraud

Points from affected submissions are reversed, the account is closed, and the record is retained so it cannot simply be reopened. That is a deliberately serious outcome, and it is reserved for cases where a person reviewed the evidence and the member had a chance to respond.

If you are flagged and you did nothing wrong

It happens, and it is fixable. Reply to the message from the address on your account, explain the circumstances — shared household, recent travel, a work VPN — and say what you were doing. Appeals go to someone who was not part of the original decision. If we were wrong, points are released and the restriction is lifted.

The goal is not a clean enforcement record. It is a panel where doing the work honestly is the best available strategy.
