# JoongAng Ilbo demo research — 2026-10-19

Requested window: 2026-04-19 through 2026-10-18 inclusive, Asia/Seoul. The first review version combines independently observed platform samples; it does not claim a complete six-month archive.

TikTok: 1,527 distinct window posts; 1,389 refreshed on October19 with exact public createTime metadata, plus 138 historical-only rows captured October17. Current scrolling ended at June5 after seven no-growth rounds at the true page bottom; historical observations extend to May19. 138 dates remain ID-inferred. Each row retains its capture timestamp and publication cutoff: October11 for the current capture, October9 for the historical capture. Public views are cumulative at capture, not views earned during the research period. No arbitrary sample count cap was imposed.

Instagram: 1,955 exact-dated posts currently observed inside the window (2026-05-07 through 2026-10-15); likes and comments are separate from views, which remain unknown. Actual official photographic carousel Deq4IbQEyQO has two slides, both inspected. It was published October19 and is used as a current design reference outside the analysis window.

YouTube: 7,305 listing IDs across Videos, Live and Shorts; this is not a window count. Exact Korean publication dates were verified for 64 window posts. The dated subset is biased toward accessible member-only metadata. Date enrichment encountered a bot sign-in challenge and stopped, so no view ranking or complete upload-frequency claim is supported.

Calendar cells show observed posts only. Blank or hatched cells are unknown, never proof of no publishing. Weekly figures are observed counts over complete calendar weeks inside the requested window. Programs are classified only from explicit series names in public descriptions; unmarked news remains unclassified. Related corporate brands are kept outside the main account statistics.

Current original article: JoongAng Ilbo, ParkHyunju, “이젠 10억도 예사…억장 무너지는 보이스피싱”, published October19 at00:02KST, https://www.joongang.co.kr/article/25470730. Its six new cards preserve annual versus partial-year periods and identify the 2024 individual case as a reconstruction. Two narrated article videos are delivered with successful Selects source analysis, actual playback-word captions, native editable drafts and matching exports.

Downloads: data/tiktok-posts.csv, data/instagram-posts.csv, data/youtube-posts.csv, data/calendar.csv. Retention, completion rate and causal editing lift were not available from these public samples.
