Ehh... it's fairly apparent from teh OP text that u were more interested in calling out and riling up supposed "fake anime fans" on Heyuri than being genuinely curious about why certain shows are commonly featured around here

If u must know, certain shows are commonly featured in users' posts bcuz (in my opinion):

- Heyuri's anime-watching users are largely interested in 2000s moe, SoL, and comedy/ecchi anime. It's a general characteristic of the userbase since day 1, which has attracted like-minded individuals whenever they've encountered the site

- those types of shows were - among many others that are far lesser known - nominated and watched on Heyuri cytube; the goal of which was to inspire more discussion, images, OC, etc. about those shows. Mission successful!

- they have been staples on Western moe-oriented imageboard communities since they aired, and are commonly brought up and recommended

- they're great shows that are classics for a reason (again, among moe anime fans - not in general). Older fans remember them fondly, newer fans watch them first to get accustomed

- it's better than the stuff that's actually popular among Western anime fans: currently-airing crap, shounenshit, Toonami shows, top-rated shows on MAL, etc. A bajillion more people have seen DBZ, One Piece, Sailor Moon, Attack on Titan, Demon Slayer, etc. than shows liek Rozen Maiden or Azumanga Daioh. U probably wouldn't want to browse a site centered around those types of shows any more than I would - hence why ur here!
