# Bot Chorus

> Public intelligence platform tracking suspected inauthentic accounts across social media. Free, open, evidence-based.

## What Bot Chorus does

Bot Chorus detects and documents suspected bot accounts using open-source data, platform APIs, and behavioral analysis. Every finding is transparent — you can see exactly which signals triggered a score and where the evidence came from.

## Key pages

- Homepage / submit a handle: https://botchorus.com/
- Network visualization (live graph of accounts and their source relationships): https://botchorus.com/network
- Activity feed (latest submissions and scores): https://botchorus.com/feed
- Full database (searchable table of all scored accounts): https://botchorus.com/database
- Reports (in-depth investigations into coordinated inauthentic behavior): https://botchorus.com/reports
- Methodology (how scoring works, signal weights, data sources): https://botchorus.com/methodology
- Legislation tracker (bot-related bills in Congress): https://botchorus.com/legislation

## Data sources

Bot Chorus cross-references each submitted handle against:
- **IRA Twitter Dataset** — 2018 Twitter transparency release (Internet Research Agency, 2,843 confirmed accounts)
- **TwiBot-20** — academic bot-label benchmark
- **Wayback Machine** — Internet Archive snapshots for bio change detection
- **FEC** — Federal Election Commission political finance data
- **Reddit** (Arctic Shift API) — comment history, subreddit concentration
- **Bluesky** — post duplication and engagement patterns
- **Mastodon** — federated post analysis
- **YouTube** — channel metadata and comment flooding detection
- **4chan /pol/** and **/biz/** — thread amplification signals
- **Telegram** — channel subscriber scale
- **Infrastructure correlation** — shared hosting/IP patterns

## Scoring

Each account receives a bot probability (0–100%) based on a weighted signal bundle. High-weight signals include confirmed dataset matches (IRA +80%, TwiBot +35%) and behavioral indicators (no-sleep posting gaps, coordinated narrative amplification, comment template flooding). Presence signals (found on YouTube, Reddit, etc.) are stored for the network graph but do not affect the probability score.

## Account pages

Every scored account has a public detail page at:
`https://botchorus.com/account/<handle>`

Pages include: score, confidence, primary signals with evidence, Wayback snapshots, raw collected data from each source, and a link to the network visualization filtered to that account.

## API (read-only, rate-limited)

Score a handle: `GET https://botchorus.com/api/score/<handle>?platform=<platform>`

Supported platforms: `twitter`, `youtube`, `reddit`, `bluesky`, `mastodon`, `telegram`, `fourchan`

Returns JSON with `bot_probability`, `confidence`, `primary_signals`, `score_summary`, and raw signal details. Rate limited to 5 requests per minute per IP.
