What Is Prolific?
Prolific (prolific.com, formerly prolific.ac) connects researchers and AI companies with real people for paid studies — everything from academic surveys to the human feedback data that goes into training and evaluating AI models. It’s very much alive and growing: the current homepage lists Google, Hugging Face, and Asana among the organizations that use it, alongside university researchers. Participants sign up, get matched to studies they’re eligible for, and get paid per study (rates are set by whoever’s running the study, not a fixed platform wage).
We checked our tracked link (/out/prolific/) directly, and it now leads to a genuine “page not found” on prolific.com — not a bot-check, an actual 404 from their own site. That tells us the old link format (a static code like 1BWVG9V9 tacked onto a URL) isn’t how referrals work anymore. When we looked at Prolific’s current referrals page instead, the program has clearly changed shape: it’s now framed around researchers referring other researchers, offering $30 in Prolific credit when someone you refer spends $125 or more, tracked through a personalized share link generated inside your own account rather than a fixed code anyone can type in. We can’t confirm whether a comparable participant-side referral bonus still exists, or whether code 1BWVG9V9 specifically still does anything — we’re not going to pretend it does when our own link into it is broken.

Frequently Asked Questions
Does referral code 1BWVG9V9 still work?
We can’t confirm that it does. Our tracked link built around that code now returns a genuine 404 on Prolific’s own site, and the current referral program we found looks structurally different (a personalized share link and a $30/$125-spend researcher referral, not a typed participant code). We’re keeping the code and old graphic here for the record, not as a working promise.
Is Prolific still a legitimate way to make money online?
As far as we can verify, yes — it’s an active, well-known platform working with real research institutions and named AI companies, not a fly-by-night survey site. How much you earn depends entirely on which studies you’re eligible for and how researchers price them.
Is the referral bonus for participants or researchers?
The current referral program we found on Prolific’s site is framed around researchers referring other researchers for account credit. We didn’t find independently confirmed details of a participant-side referral bonus as of this check — if Prolific offers one, look for it inside your own account rather than a code from an old post like this.
