I do not have much to say...But for now avoid this site.
Waste of time!

They opened up a project named project Aid and after hours of working on the project and submitting tasks, they removed the project without paying a dime

I lasted a day with this company. I applied through LinkedIn as a doctoral researcher, attracted by the advertised pay rate of $100 to $180 per hour. However, what I earned over the course of my day with this company was $120 total, barely above the minimum wage for my state – hence my exit. The reasons for this were: undisclosed task caps that were never in the job description; an automated checker that blocked the most sophisticated prompts (precisely the work PhD researchers would naturally produce); domain closures without notice; compensation tied to work accepted rather than work actually done; vague promises of scaling that never materialised. The effect of all this was wage suppression, and a feeling that high-quality data from PhD-level contributors had been extracted without fair recompense. For these reasons I'd urge researchers to be cautious about onboarding with this company, or to give the company a miss entirely.
