At Prolific we are committed to providing the highest level of data quality to our researchers. If you ever have any concerns about the level of data quality you are receiving from us please do not hesitate to get in touch with us directly using the button at the bottom of this article.

How does Prolific currently review accounts?

We use a variety of tools to help make sure you get excellent data quality on Prolific. These include participant verification, IP and ISP reviews, and continued account checks. Unfortunately, sometimes low-quality submissions still happen. We're keen to look into these participants as soon as we can so we encourage you to report them to us.

We have a blog post available that explains some of the steps that we take to ensure the quality of our participant pool.

Report concerns to our Support Team

You can contact our Support Team directly to highlight any participants or submissions you want to report.

Rejections count against participants, so if you have already rejected the participant then in most cases there is no need to also report them to us. If you wish to discuss concerns with the Support Team, or need any action to be taken in relation to your study, please get in contact using the button at the bottom of this article.

We will look into any participants reported and take appropriate action.

Please note that NOCODE, timed out and returned submissions are not valid reasons to report participants. Please see the linked articles for further guidance.
