At the end of their day, the people they care most about are premium users and NC buyers. I don't think you'd really be on their care factor radar, unless you spend vast amounts of money on the site.

I'm a premium user ;) I have never spent on NC though, so I'm still small beans in that matter. On the other hand, at least until NC came along, most revenue was through advertising, and that is entirely dependent on page views. So there's another thing to wonder about, ad revenue vs. NC revenue?
