Vantaggi
It's flexible and sometimes the money is OK. I got paid most of what they owed me.
Svantaggi
Generally disorganized. The task I was on was one of the more highly paid ones but it was almost impossible to actually do in the allotted time. You aren't supposed to use AI but I think people must. The tasks run far over the time they are supposed to take. The human review system also seemed almost arbitrary. Reviewers did not have the subject matter expertise they claimed to. You will make less than the advertised hourly rate because the tasks routinely take longer than they say they will. If they have averages that are lower, those people are either not submitting accurate hours (there is incentive not to) or are using AI to train AI, which is a bigger problem (but not yours).
