Userinterviews is the best 🥹

Just got this email https://imgur.com/a/EWgRmKr after finishing a super easy and fun diary study. I thought it was very sweet and made me smile.

Does anyone know what kind of participant quality rating system they use behind the scenes? I’m sure there’s gotta be one, I’ve had an account for over a year and never lucked out with studies until last month when I got selected for a short interview about a very niche subject. I’ve made $525 since!
