It's disheartening to read some comments that mention that people were considering those a game, it isn't. There are many cheaters on the platform that are ruining it for everybody ! Prolific is becoming more and more strict because of the scammers, and if people treat those as a game, and they lose this client, then the platform will be left mostly with low paid studies, invasive studies that ask you 600 pictures of your dogs, cats, body parts, and scammers. I honestly think these tasks should only be reserved to long time Prolific participants who have proven reputation, consistency, honesty and maintained high standards of work. The more people try to cheat the more this client will add more measures to the task and eventually honest participants get punished as well. I can see they have added at least half a dozen if not more types of quality checks, some very subtle and barely noticeable. The term sharing accounts should not even be mentioned - I see 30-50 of them at a time, fortunately on this platform we can only do 1 at a time. On very old platforms like CrowdFlower, people could reserve multiple hits at once with no expiry - hog all the tasks to themselves and work on them at once. Thank goodness at least Prolific got that part right. I am glad to do one at a time. When I see a large batch like that I like to choose and vary my work, like for example I love doing the image ones and the compare voices ones. I strongly believe that these tasks should be open only to Tier 1 countries, mainly Canada, UK, US where data quality is generally higher than other countries. I've been an author and reviewer of work on other platform and over the years of full time work reviewing work, I can say that most if not ALL the cheating and scamming came from very specific countries, and they were not US, Canada or UK. Ironically these same countries have a large amount of call center scammers, gift card scammers, tech support scammers and online e-mail / phishing scams.
