Alright, so watching through all the research done for this thread, I am quite impressed about the amount of detail. I have one question though: have you only counted the safe-for-work art, or everything with the tag representing that character? Because I think you need to change some settings if you want to see the ABSOLUTE ALL bits of art from an artist (in my case, since I have the "hide anything R18" option active, I think I am missing in average like 20-30%, sometimes even 50% or more out of what a creator does).
Also, I think there should be counted the idea that there might be posts with multiple images in that post depicting the same character. Like saying there is a post with the tag "Reimu", but the post itself has multiple images of Reimu in it. Or group images, where you have too many characters to tag them all (max limit tag is 10 on Pixiv, compared to 30 on DeviantArt for example)
Like in this image. I have multiple 2hus, yet at how many there are, I did not manage to tag any of them. Therefore, the image only bears the "Touhou" tag in the upload
But for a bit of personal note, this is what I can come up with. Going by my favorite characters, the situation is a bit interesting:
- Hieda no Akyuu: 489 (a bit disappointed, but at least I brought my own contribution with an art piece there)
- Eiki Shiki, Yamaxanadu: 960 (also a bit low, but I can see why; again, contributed with one drawing)
- Renko Usami: 1486
- Maribel Hearn: 1252
- Youmu Konpaku: 5307
- Yuuka Kazami: 1947
- Mayumi Joutouguu: 895
- Raiko Horikawa: 394 (come on, I really think she deserves more)
- Tenkyuu Chimata: 1199 (maybe I can make it 1200 if I actually upload one drawing I have done a while ago)
- Utsuho Reiuji (Okuu): 1418
- (Bonus - former top 10 members, still enjoyed) Junko: 959
- Hecatia Lapislazuli: 831
- Iku Nagae: 679
