In my opinion, they ruined it for themselves. They started changing the qualifications they used to vet workers. Once upon a time I had a qualification with them for giving good feedback, or something to that effect. I was actually able to get the HITs when they posted. They removed the writing requirement, they lowered the pay, and lowered the bar to 100 approved HITs. What did they think was going to happen? I don't even bother trying to get them anymore when they post because they get absolutely mobbed. I genuinely love medical stuff and was interested in providing quality feedback, but they seemed to stop caring about that. You're right in that a few people probably ruined it, but CSats themselves left the door wide open for them to do so.
