Heyuri is not strictly a rorikon website - Our Off-Topic board is housing bunch of adult (JK+) ero as well!
Looking at the first page, only thread that bats to my eye is faganon's Muhammed thread
I think everyone who has a problem with anything else on the front page of Off-Topic either thinks too deeply about what others are fapping to, cares too much about contemporary western ethics, or just too new to the internet

I also think there are hardly any "pedo-related" threads on Heyuri anyways, at least not enough to be called "bajillions". Maybe it's something ur not used to see elsewhere, so your selective perception makes u think a higher percentage of the existing threads even include a loli pic in them? Out of 50 newest threads on Off-Topic, I see
- faganon's muhammed thread: https://img.heyuri.net/b/koko.php?res=130104
- roripantsu onigiri thread: https://img.heyuri.net/b/koko.php?res=130055
- a no-reply minami-ke pantsu's image's thread: https://img.heyuri.net/b/koko.php?res=130046
- a thread with an onegai twins image: https://img.heyuri.net/b/koko.php?res=129970
- finally 49th thread is about fat loli, only thread I'd call for the lolikon: https://img.heyuri.net/b/koko.php?res=129682
10% are pedo "related" threads (20% of which is by faganon)
from a sample of 50 threads, I can say 2% of all threads on Off-Topic are for our lolikon users.
