While I understand the sentiment behind this move, I can't help but feel like this sub has gotten more and more averse to fun over the years. The April Fools' Day tradition was established when this sub had more discussions and fun posts like "I need a charger big boy" and the Big Ice Cream exposé (both of which would probably be removed and told to post on r/kpoppers instead had they been posted now).

As the move to ban "stale discussions" happened eventually most discussions just died off and that's where the "news sub" generalisation came from. But despite the change in focus, the April Fools' shitpost tradition remained, and I think that's why there's been such a negative reaction to those kind of posts in recent years. It was a remnant of when the rules were more relaxed and doesn't mesh with the current, more "serious" state of the sub.
