Pros
Great for people with disabilities for whom leaving home / working full-time is difficult or impossible. Able to work any hours of the day, so you can fit it around your schedule as needed. Decent system for reporting unavailability. Online spaces to connect with other raters if desired, or you can keep to yourself if that's more your speed. No micromanagers. Lots of resources and guidance if you need help understanding a task. Most of the work is very intuitive, and anything harder usually comes with thorough guidelines and examples to demonstrate.
Cons
Pay could be more competitive. Weekly minimum number of hours not quite as friendly for people with chronic illnesses. Task shortages are common, especially at certain times of the year, meaning there could be days or weeks where there simply is no work for you to do. Part-time by design so no benefits.
