I can see where some people are acting as publishers for other authors or are commissioning others to create books for publishing so they can upload multiple books at a time. I'd be interested in knowing who can hit the limit and why.

Quality is another thing. A while back my library was purchasing tech related kindle books just because of the title. I know this since I borrowed one and it was just garbage. It was a combination of Wikipedia articles plus stuff that was gathered from the web with no editing.

But yes, I see your point.
