I just did a terribly bad paying task at prolific and I finished it just so I could leave the feedback I left in the tell us about a time section, then I submitted then returned it from my dashboard. 40 cents for 15 min work, I told them how about paying a decent hourly on their study, just because we are online workers does not mean we deserve less pay, and I told them to feel free to email me back and tell me if they would work their survey for that pathetic pay...
any of you guys n dolls ever just finished a survey/study just so you could submit your "let me tell you something about your study? then returned it lol
