Are they training their AI with our ID verification?
Honestly, this whole thing with Prolific feels sketchy to me.
They ask people for government-issued IDs and face scans/biometric verification, then a lot of people seem to get hit with vague “failed verification” messages with no real explanation and no meaningful manual review process.
In my case, I never even got to complete a single study. My account was permanently rejected during verification. I appealed it and got the same copy-paste response saying the decision was final and they couldn’t help further.
What makes it even weirder is that when I later tried making another account. Four months later (yesterday) I received a invite email. Upon clicking the link they somehow detected me again almost immediately before I even entered a phone number on the new account. That means they are clearly retaining and matching some kind of identity/device/biometric information even after accounts are supposedly “closed.”
So naturally it makes me question:
What exactly are they storing?
How long are they storing it?
What are these ID scans and face scans actually being used for behind the scenes?
At this point, I personally think this company may be using all of this verification data to further train or improve AI/fraud-detection systems while ordinary users get permanently locked out with no transparency and no real way to challenge mistakes.
And before anybody says “your ID must’ve been fake” — my ID is legitimate. I use it to fly, bought a car with it, and it has the REAL ID emblem. I scanned it using an iPhone 17 Pro Max, so quality wasn’t the issue either.
I’m not the only person I’ve seen complain about being instantly rejected with no clear explanation. Has anyone else experienced this?
