What kind of logic is this? If a topic is pinned, it’s important and always under any circumstances ought to stay on top. Unpinning something just by scrolling in a forum design that relies so heavily on scrolling or deliberately with a click makes the forum a lot less comprehensible and less readable.
This auto-unpin box should be opt-in, not opt-out because this option makes the forum experience a lot less feasible and coherent.
How does this even work? I had this option enabled and scrolled to the bottom of this forum until it said “No new posts. Why not create a topic” but the 2 pinned topics at the top (change log and announcement) are still pinned.
