Since she could write, she mostly did writing assignments (which I suspected were for SEO Web sites), in which they tell you a topic and how many words to write, you research and write the article, and you get paid a pittance. But $2 will buy steel-cut oats for the day.
Her time should've been worth more than $1-$2/hour, and I don't like the idea of companies arguably exploiting desperate people this way. Though it's not just companies: university researchers sometimes use Mechanical Turk workers to process data, and as research subjects.
