In my opinion, as a NSFW artist keeping an eye on what is popular and what isn’t… the fine arts badge for explicit and questionable images should be between 400~300.
I am not sure though, there is a fair amount of NSFW art that I think is artistically very tasteful, but also a lot of things that is just blindly focusing on body parts, if that’s the kind of art you don’t want to reward.
There’s a fair bit of stuff focusing on body parts with a score of 300, but around 400, it’s mostly emotive porn that makes it up there. 350 has an equal balance between stuff I consider ‘smut’ and ‘erotica’
Dunno what you guys want in regards to quantity of pics uploaded, but I think 400, 350, or 300 should be a good number to shoot for with quality
Also, I will be happy if I get an artist badge
