Think of #rms as a filter on the wider porn caption caption archive: same submission pool, but slimmed down to the exact register you searched for.
Score is the primary sort, freshness the secondary — meaning a #rms post from six months ago can still lead the feed if the community keeps returning to it, while brand-new drops still surface as they earn saves.
Because engagement counts (likes, saves, shares) are live per post, the page keeps sorting itself even without editorial intervention — the top of the feed reflects real porn captions demand today, not last month.
As more creators publish under #rms, this page rebuilds itself daily with fresh title, alt, caption and tag combinations — meaning what you saw yesterday is not what you'll see tomorrow.
