## What it is
A Node.js proof-of-concept tool that polls Facebook's online/offline status to infer and visualize friends' sleep patterns. It consists of a scraper and a local web server that displays the collected data in the browser.

## Use cases
- demonstrate privacy risks of social media presence indicators
- track when Facebook friends are online to infer sleep schedules
- research OSINT techniques using online status data
- visualize collected online/offline activity over time

## When to choose
- you want a concrete demonstration of social media privacy implications
- you're researching what online-status data leaks about users
- you need a simple Node.js scraping plus visualization example

## When to avoid
- you need a maintained tool — the project is abandoned and Facebook's API changes likely broke it
- you want production-grade or ethical monitoring of real people
- you need anything beyond a proof-of-concept demo

## Facets
- artifact type: application
- maturity: abandoned
- function: web-scraping, data-visualization, http-server, analytics
- domain: privacy, social-media, osint, web-development
- platform: cross-platform
- tags: facebook, sleep-tracking, privacy-research, scraper, proof-of-concept, nodejs, web-server
