Fair points. I don't scrape/spin any content, and I would argue that it's easier to write 500 words than 50, but I can see how my content might run afoul of an automated system. Plenty of the comments on this thread make similar points.

Ironically, I know of a scraper site that mirrors Amazon's bestsellers list, reformatted as blog posts: https://gistgear.com - and it's growing like gangbusters.
