When I visit kbin.social, I see new posts regularly. On other servers posts stay on the frontpage for multiple days. This is also true if I switch their sorting to “hot”. So that is probably not the difference.
What is kbin.social doing differently?
I have an issue on Lemmy.world when I sort by Top-> day the top posts will be bumped down by brand new posts with 1 upvote, I assume people are instantly upvoting themselves and that’s messing with something in the code
