Not sure if Kbin has the same filtering options as Lemmy, but the “Top Hour” etc. filters can be pretty useful to see top content on a sliding scale of time which will filter out the older stuff:
The algorithms that sort by “Hot” since the 0.18.x release of Lemmy seem to be doing a way better job of showing timely content now though; much better than earlier versions in my experience.
