They pay a pittance, often mislead about the time one needs to sacrifice and I don't like them.
They don't respond in any meaningful manner to anyone about anything. They are devoid of transparency and totally scammy.
Tip for consumers: They bunch surveys together, you sometimes complete a dozen surveys and get paid for one. They steal about 90% of what you earn. It's disgusting and I am doing all I can to get this dodgy industry regulated as they have personally made me quite angry.
