How "Active" works on this page. A listing flips to
inactive via mark_stale(days=7) β a time-based sweep
that runs after every scrape, not a live check against ss.com. So a
listing that was last seen 6 days ago stays marked active until the next
scrape session misses it, even if the seller already pulled the ad.
Combine the Active filter with First seen below to
gauge how stale a row really is. The proposed session-bound logic lives
in Wiki Β§7.
