This is not real grass. And that’s not a real comment, either.

Sure, the microtasks are usually tedious, but they need humans to do them and they provide an income stream, albeit a small one, to people who have no other way to make a livelihood.

As detailed in an ArXiv paper, Zhao and colleagues found that this “evil crowdsourcing on a very large scale” consumes the vast majority of business on crowdsourcing sites: On the second-largest such site in the US, ShortTask, 95% of the transactions were crowdturfing (the largest, Amazon’s Mechanical Turk, which actively roots out such tasks, had 12%). Zhubajie and Sandaha, major Chinese crowdsourcing sites, turned out to be 88% and 92% ‘turfing tasks, with more than a million dollars paid for crowdturfing each month on Zhubajie alone. Read More
