## Identity
- platform: x
- handle: pirrer
- platform_url: https://twitter.com/pirrer
- entity_type: creator
- person_id: Cross-platform identity not resolved for this creator.

## Reach
- followers: 25098
- following: 1375
- posts_total: 17723
- posts_observed: 15
- posts_per_day: 2.509
- account_age_days: 7063
- verified: true
- size_tier: koc

## Engagement
- status: peak_post_only
- peak_post_engagement_rate: 0.00287
- best_post_interactions: 72
- measurement_source: x_post_interactions
- measurement_formula: interactions on one post — likes, or likes + reposts + replies depending on the discovery path (the two are not distinguishable in the stored data)
- comparable_pool: peak_interactions
- status_note: We have only the single best observed post, so no mean exists. peak_post_engagement_rate is an UPPER BOUND, systematically higher than an average — never compare it against an average rate.
- unit_note: engagement_rate and peak_post_engagement_rate are ratios (0-1); avg_interactions_per_post and best_post_interactions are absolute counts. Read status before reading any number: a null rate has several different causes and status says which one applies here.

## Evidence
- [x_pirrer#06459768] 你的員工，是不是還在用私人 LINE 跑公務？ (https://twitter.com/pirrer/status/2067455599634497935)
- [x_pirrer#517aebbe] 離職的時候客戶名單跟著手機一起走，重要文件散在每個人的私人對話裡，下班還被工作群組訊息轟炸，這幾乎是台灣九成企業的日常。
- [x_pirrer#3206e655] 我會特別注意到這題，是因為一個認識好幾年的朋友。Raccoon AI 的創辦人 James  Yi-shin Chou 我兩年多前還正式訪談過一次，聊完最記得的，是他做東西「能長大」的本事。
- [x_pirrer#a389bd11] 他早年接了一個法國 app 叫 Zenly（冰棒），剛進台灣的時候幾乎沒人用。結果他帶著團隊一年內把它從社交榜二十幾名做到前五，整個亞洲月活衝到四千多萬。靠的不是燒廣告，是去摸清楚年輕人為什麼想知道朋友在哪、想比誰朋友多，再把那個心理做成一個一鍵分享的功能。
- [x_pirrer#e4ce1b41] 後來他接了 Zendesk 的客服系統代理，一做就是快十年的客服 SaaS。所以當他現在跳出來做 AI 客服、做企業的數位員工，我一點都不意外，這是他十年客服底子長出來的

- quality.authenticity_score: source_type=heuristic, confidence=0.5, freshness_days=79, method=Profile-shape heuristic from a single snapshot (follower count, following ratio, account age, posting volume, verification), reduced for engagement red flags where post engagement was collected. Where only a follower count is available the score saturates at 58. — The input set differs by platform; do not compare this score across platforms.
- quality.koinon_bd_grade: source_type=ai_inferred, confidence=0.5, freshness_days=117, method=llm_partner_fit_classifier + fit_score >= 0.6 AND authenticity >= 60 => A; fit_score >= 0.4 AND authenticity >= 45 => B; else C. authenticity < 30 or a promotional-pattern flag => quarantine. — Koinon partner-outreach fit, not creator quality.
