My 16-year old son has a classmate who has made about $50 or
so writing spam questions for Quora. Some of these questions were astonishingly stupid, the kind of writing that I would have fired a spam writer back in the day that I hired spam writers.
It wasn't clear if he was working for Quora or working for somebody who wanted to spam Quora, but the damage is done.
Honestly, if you 'incentivise' someone to post on a community site (whether via money, exchanges or free stuff in general), the quality of their work will usually be terrible. What do you expect when you ask non experts to post reams of topics about things they haven't got the slightest clue about?
I always wonder who's doing that and why. Quora does pay people to write questions, but the pay is supposed to be tied somehow to the quality of the answers. Maybe it's more a quantity thing, as dozens of people jump in to give answers to the basic arithmetic questions in my feed.
