sometimes people elect to upload as much as possible of their favorite characters/copyrights and it inflates their numbers massively. look closely and you'll find that 65% of Scaramouche (Genshin Impact) was contributed by a single user, quite the impressive feat.
As a fan of Hyakkano, I can safely say that about a third of the series' presence here is thanks to WorldEndDominator's posting, though tbf there might have been more prevalent people before he got into it.
