I tried as an article writer in Odesk.com as an article spinner and it was a nice online job before. Search engines can be very helpful because they contain large amount of data and articles that are very informative and helpful as well, in this way it can give us a lot of knowledge and i'm sure you agree with me guys.
Getting work on upwork is usually not great for the freelancer lots of dodgy stuff going on there and they like to lowball freelancers, was never worth it for me. Article spinning isn't really very SEO friendly though. I agree once you get into the real nitty gritty you can find yourself diving down a rabbit hole of note
