time helps but doesn't really play THAT big a factor in porn. There's mountains of day 1 girls who are unpopular
That aside I had a suspicion that Aegir wasn't that popular and I will concede to the fact that Chesire has twice the amount of porn as Aegir
I was mostly comparing meta/popularity poll results to the porn results:
Atago had like 3.7k on danbooru
Sirius had 3.1k on danbooru
Bremer had like 600 pics
Kashino had 900 pics
NJ had like 400 pics (Albeit pixiv now says 600 IIRC)
