Why YSK: I use the web version of Lemmy both on desktop and mobile. By going directly to the 2nd page of posts, I get rid of both the neverending stream of new posts and of the same old posts that keep sticking to the 1st page. It works for all the filters: active, hot… No need to scroll down, just change the number in the end of the URL from 1 to 2 and save it to favourites or whatever.
You can also see the first page no-scroll by changing the number from one to zero. Not sure why this stuff works, but hey, it does the job until future updates are in play.
