Hong Kong Himalaya Bio's marketplace subforum logged 73 posts in the current window, a 329% increase over the prior period — but the activity traces to a narrow base. Just three authors account for the surge across eight threads, with vendor-originated material breaking down into two promo posts, two CoA postings, and four discussion entries against a backdrop of community replies that did not scale to match.

The promotional cadence is template-driven. Vendor representative a community member (HHB) opened the window with a near-identical contact block: "The promotion for this event is still ongoing. All products are in stock. Hurry up and place an order," followed by WhatsApp, Telegram, and Discord handoffs to off-thread channels. The second and third promo posts reproduce the contact block verbatim, swapping only the Discord invite.

Community uptake on the promo threads is measurable and thin. Top non-vendor voices a community member, a community member HKfatcat, and a community member Michelle King logged two to three posts each across two to three threads, and reaction counts across the entire cohort total one — a single reaction registered against a community member HKfatcat's contributions. The broader subforum ran [8, 5, 1, 2, 7, 3, 2] daily posts over the last seven days, a 4.0 daily average against a window down 60% in author count versus the prior period.
