There were some leaked FA statistics that show that, although there is a significant more amount of SFW content than NSFW content, NSFW was consistently shown to generate more views and attention.

It's just.. The nature of the fandom? Haha
I definitely prefer SFW work to NSFW in most cases, though.

Yesss. That's unfortunate in a way. I've met artists that say they feel they have to draw diff in order to make money. Anywho. I didn't even notice the SFW/NSFW button for the longest time, to tell you the truth! Then I turned SFW off and FA became an entirely different website.
