# MEDIUM NETWORK ANALYSIS — Keith Birney Shell Account Cluster
## Forensic Social Media Investigation
**Date:** February 21, 2026
**Subject:** Medium.com account @keithbirney (Keith Birney, spouse of Redmond Mayor Angela Birney)

---

## EXECUTIVE SUMMARY

Keith Birney, husband of Redmond Mayor Angela Birney, maintains a Medium.com account (@keithbirney) that is the hub of a network of approximately 30 accounts. Nearly all accounts in the network:

1. Have **zero published articles**
2. Were created within the **same two-week window in November 2019** — beginning 6 days after Angela Birney was elected mayor
3. All **follow each other** in a tight cluster with nearly identical follower/following ratios (~55/55)
4. Have **no bios, no content, no activity** beyond the follow relationships themselves

This pattern is consistent with a **synthetic follow network** (also known as a "follow farm" or "astroturf network"). The purpose of such networks is not publishing — it is establishing a social media presence that appears legitimate at surface level, or using the platform's private messaging and notes features for communication outside standard channels.

---

## METHODOLOGY

1. **RSS Feed Analysis:** Medium's public RSS endpoint (`medium.com/feed/@username`) was queried for each account to verify article count. This endpoint is not blocked by Cloudflare and returns reliable data.

2. **Wayback Machine Dating:** The Internet Archive's CDX API (`web.archive.org/cdx/search/cdx`) was queried for the earliest archived snapshot of each account's Medium profile page. This provides a minimum creation date for each account.

3. **Network Crawling:** Playwright (headless Chromium) was used to scrape follower/following lists from each account in the network to map the relationship graph.

## THE NOVEMBER 2019 CLUSTER

### Timeline Context

- **November 5, 2019:** Angela Birney elected Mayor of Redmond, WA
- **November 11-30, 2019:** 15+ zero-article Medium accounts created and interconnected

| @jeffhuang_3923 | Jeff Huang | **Nov 30, 2019** | 0 | 49 | 54 |

**15 accounts created in 19 days. Zero articles across all of them.**

### Additional Accounts Not Yet Archived (likely same period)

| Account | Display Name | Articles | Following | Followers |
|---|---|---|---|---|
| @samuelhoang | Samuel Hoang | 0 | 56 | 53 |
| @santhoshraman | Santhosh Raman | 0 | 48 | 56 |
| @georgechung_2988 | George Chung | 0 | 24 | 50 |
| @baiyangliu | Baiyang Liu | 0 | 16 | 33 |
| @anujbindal | Anuj Bindal | 0 | 56 | 55 |

These accounts were not archived by the Wayback Machine but share identical behavioral patterns with the November 2019 cluster (zero articles, similar follower/following ratios, interconnected).

### Recent Additions (2025)

| Account | Display Name | First Archived | Articles | Following | Followers |
|---|---|---|---|---|---|
| @xinliu_96302 | Xin Liu | **Oct 17, 2025** | 0 | 41 | 55 |
| @heyjchu | Jon Chu | **Nov 4, 2025** | 0 | 10 | 53 |

The network is still being actively maintained. New zero-article accounts were added in October-November 2025.

### Legitimate Accounts in the Network (cover)

| Account | Display Name | First Archived | Articles | Notes |
|---|---|---|---|---|
| @carolynwei | Carolyn Wei | **Aug 2, 2016** | 6 | Predates cluster by 3 years — likely a real person |
| @ijeomaoluo | Ijeoma Oluo | (established) | 10 | Published author — real account used for credibility |
| @mvernal | (StarkWare related) | (established) | 10 | Real account |
| @benthompson | Ben Thompson | (established) | 1 | Real account |
| @amitaggarwal_89796 | Amit Aggarwal | (established) | 1 | "Why we built The Yes" — real founder |
| @poshanlife | (food/GHG) | (established) | 3 | Real account |
| @vimwe | (end game) | (established) | 2 | Real account |

A small number of accounts with actual articles are followed by the cluster. This is a standard astroturfing technique: following real accounts gives the network a veneer of legitimacy and makes the follower/following ratios look less artificial.

---

## BEHAVIORAL ANALYSIS

### Follow Ratio Clustering

Normal Medium users have highly variable follower/following ratios. Writers might have 10,000 followers and follow 50. Readers might follow 200 and have 3 followers.

The Keith Birney network accounts overwhelmingly cluster around:
- **Following: 48-56** (mode: 56)
- **Followers: 50-56** (mode: ~53-55)

This near-1:1 ratio across 20+ accounts is a statistical signature of accounts that exist primarily to follow each other.

### Zero Content Production

Of approximately 30 accounts in Keith Birney's immediate network:
- **~23 have zero articles** (77%)
- **~7 have 1-10 articles** (23%, and these appear to be real accounts followed for cover)

A network where 77% of members have never published a single article on a publishing platform is not organic.

### No Bios

The overwhelming majority of the zero-article accounts have no bio text, no website links, and no identifying information beyond a display name and (in some cases) a profile image.

## SIGNIFICANCE

### Why This Matters for the OFH Investigation

1. **Platform Choice:** Medium is not subject to FOIA, public records laws, or PDC disclosure requirements. It is a channel that exists entirely outside government transparency mechanisms.

2. **DM Capability:** Medium accounts can send private messages ("notes") to accounts they follow. A network of interconnected accounts provides a private communication channel.

3. **Timing:** The network was created the week Angela Birney became mayor. If it was created for legitimate purposes, those purposes have not manifested in 6+ years of zero published content.

4. **Technical Sophistication:** Keith Birney holds Microsoft patents in web indexing and search technology (US7502773). He has the technical expertise to construct a synthetic network that would pass casual inspection.

5. **Pattern:** This follows the same concealment pattern identified in the FOIA analysis — channel switching ("give me a call"), moving communications off-record, and using channels that are not captured by public records requests.

### Keith Birney's Public Profile Anomalies

| Platform | Status |
|---|---|
| **Medium** | Account with followers, zero articles, hub of shell network |
| **LinkedIn** | Sparse profile for someone with patents at Microsoft and Facebook |
| **Twitter/X** | Account exists (@keithbirney), activity unknown |
| **WA State Business Registry** | No IT company registered under his name |
| **PDC Campaign Finance** | Zero political donations in database |
| **PDC F1 Financial Disclosure** | Employer listed as Facebook (2020), then **"not listed"** (2024) |

## THE @json.knight BACKLINK FARM

### Discovery

The account @json.knight ("JSON Knight") was found connected to @keithbirney's profile. Despite appearing to be a recipe blog, it contains no actual recipes and serves as a delivery vehicle for a network of fake persona websites.

### Account Profile

| Field | Value |
|---|---|
| Username | @json.knight |
| Display Name | JSON Knight |
| Medium User ID | 5857faeb4b9 |
| Articles | 10 (all fake "recipes") |
| Posting Window | Dec 3, 2023 — Jan 4, 2024 (33 days, then abandoned) |
| Wayback First Seen | **April 26, 2025** (16 months after posts — zero organic discovery) |

**Note:** The username "JSON" is JavaScript Object Notation — a data format used by software engineers. This is a developer pun, not a real name. A real product management writer named Jason Knight uses @json-knight (hyphen) — different account, different user ID.

### The "Recipe" Content

All 10 articles follow an identical template:
- A title (e.g., "Bread — Corn Muffins")
- One stock photo
- One sentence caption
- **No ingredients. No instructions. No recipe whatsoever.**

Posts are spaced 2-5 days apart, consistent with automated scheduling. All published in a single burst, then never updated.

### Hidden Hyperlinks in Stock Photos

Four of ten articles contain **hyperlinks embedded inside the stock photos** — invisible to casual readers but creating backlinks for SEO:

| Article | Hidden Link Target |
|---|---|
| Basic Beurre Blanc (Jan 4, 2024) | `www.milesriley.com` |
| Instant Pot Sweet Potatoes (Dec 19, 2023) | `www.estherhampton.com` |
| Chicken Spaghetti (Dec 15, 2023) | `www.pierremercer.com` |
| Cookies — Chunks (Dec 10, 2023) | `www.ralphbishop.com` |

These links were confirmed directly in the RSS feed content — they are `<a href>` tags wrapping the `<img>` tags.

### The Fake Persona Website Ring (15+ Domains)

Following the cross-links from the four target domains revealed **15 fake persona websites** organized in three clusters of five:

**Cluster A** (linked from milesriley.com):

| Domain | Fake Persona |
|---|---|
| milesriley.com | "Miles Riley" — photographer |
| teaganwarren.com | "Teagan Warren" — personal page |
| ashtonwalsh.com | "Ashton Walsh" — personal website |
| coltonadams.com | "Colton Adams" — web programmer & designer |
| evalittle.com | "Eva Little" — chef |

**Cluster B** (linked from estherhampton.com):

| Domain | Fake Persona |
|---|---|
| estherhampton.com | "Esther Hampton" — dietician |
| bentleyhale.com | "Bentley Hale" — personal page |
| bernardcrosby.com | "Bernard Crosby" — personal page |
| meredithowens.com | "Meredith Owens" — personal page |
| janellesteele.com | "Janelle Steele" — personal blog |

**Cluster C** (linked from ralphbishop.com):

| Domain | Fake Persona |
|---|---|
| ralphbishop.com | "Ralph Bishop" — automotive blog |
| kaylawallace.com | "Kayla Wallace" — chef |
| ethanfreeman.com | "Ethan Freeman" — personal page |
| judyromero.com | "Judy Romero" — personal page |
| debraolsen.com | "Debra Olsen" — personal page |

**A 16th domain** (`vanessanewton.com`) was discovered via reverse DNS — same registrar, nameservers, and update timestamps.

All sites are template/placeholder sites with stock imagery, minimal content, and — critically — they **all cross-link to each other**, creating a closed loop of fake authority signals.

### WHOIS Analysis: Single Operator Confirmed

WHOIS records for all 15 domains prove they are controlled by **one entity**:

**Registration:**
- **100% same registrar:** NameCheap, Inc.
- **100% same privacy proxy:** Withheld for Privacy ehf (Iceland)
- **Sequential registry IDs:** The March 2018 batch (ethanfreeman, ralphbishop, judyromero, debraolsen) have Verisign Registry Domain IDs 2233894821–2233894849 — registered within **14 seconds** of each other (one shopping cart checkout)

**Three bulk-purchase waves:**

| Wave | Dates | Domains | Hosting |
|---|---|---|---|
| Wave 1 | Nov 2016 + Mar 2018 | 5 domains | MojoHost (Miami FL) |
| Wave 2 | Jan 3-11, 2019 | 5 domains | Vacares LLC (Dallas TX) — all resolve to same IP `84.247.3.129` |
| Wave 3 | Oct 1-7, 2020 | 5 domains | MojoHost (Miami FL) |

Waves 2 and 3 show **one-domain-per-day staggering** — likely to avoid bulk registration flags.

**Maintenance:**
- On **August 6, 2025** between 16:36–17:01 UTC, **14 of 15 domains** were updated in a single session
- On **January 7, 2026** between 16:41–16:42 UTC, the remaining domains were updated together
- This proves a single NameCheap control panel managing all domains

**Hosting:**
- Only two providers: **Vacares LLC** (AS13820, virtual office in Dallas TX) and **MojoHost** (AS27589, Miami FL)
- The five Vacares domains resolve to identical IP: `84.247.3.129`

### Technical Significance

This operation — using Medium articles as backlink delivery vehicles for a ring of fake persona websites — requires expertise in:
1. **SEO/web graph manipulation** (backlink farming, cross-linking)
2. **Domain registration at scale** (bulk purchasing, staggered to avoid flags)
3. **Web hosting infrastructure** (multiple providers, separate IPs per cluster)
4. **Content seeding** (scheduling posts, embedding invisible links)

Keith Birney holds **US Patent 7,502,773** in web indexing and search technology, filed while working on Bing at Microsoft. The technical fingerprint of this operation is squarely within his documented expertise.

## RECOMMENDATIONS FOR LEGAL REVIEW

1. **Screenshot and archive** all accounts in the network immediately (accounts can be deleted)
2. **Cross-reference names** against Microsoft, Facebook/Meta, and City of Redmond employee directories
3. **Subpoena Medium** for account creation dates, IP addresses, email addresses used for registration, and any private messages sent between accounts in the network
4. **Add to public records request:** Any City of Redmond communications via Medium.com or any accounts associated with Keith Birney
5. **PDC complaint consideration:** If the network was created to facilitate undisclosed political coordination, it may violate Washington's campaign finance disclosure laws
6. **Check other platforms:** The same pattern may exist on Twitter/X (@keithbirney), Reddit, or other social platforms
7. **Subpoena NameCheap** for registrant identity behind the 15+ fake persona domains — the privacy proxy (Withheld for Privacy ehf) shields the owner, but NameCheap holds the real registration details
8. **Subpoena Vacares LLC and MojoHost** for hosting account details tied to the fake persona domains
9. **Archive the @json.knight Medium account** and all 15+ fake persona websites before they can be taken down
10. **WHOIS monitoring:** Set up alerts for domain expiration/transfer on all 15 domains — the operator may attempt to let them lapse or transfer them once aware of this investigation

### Not Yet Identified
@chaoy, @pdtpatrick, @loe, @mikemastrangelo, @samuelhoang, @evakness, @peterdevries_29921, @jeffhuang_3923, @baiyangliu, @georgechung_2988, @heidinarayan, @xinliu_96302

### Key Observations
- **100% tech industry** — every identified person is Microsoft or Facebook
- Split along Keith Birney's career path (MS → FB)
- The Bing Search team members have specific expertise in **web graph analysis, search ranking, and link authority** — the exact skills needed to build the @json.knight backlink farm
- **None** of the identified individuals donated to Angela Birney's campaign per PDC records
- **Jon Chu** (Khosla Ventures) invests in PropTech — relevant given the OFH property's Downtown Core zoning (FAR 8.0, 144ft height limit) adjacent to Nelson Legacy Group's 22-acre development site
