    DISCORD.js-selfbot

    DISCORD.js-selfbot

    An unofficial discord.js fork for creating selfbots

    DISCORD.js-selfbot is an archived Node.js library based on discord.js that targets Discord user-account API behavior instead of normal bot accounts. It exposes structures for messages, guilds, interactions, status, activity, voice, video, and other user-specific Discord features. The project was built around Discord API v9 and backported selected functionality from later discord.js versions. It includes documentation, examples, tests, and npm distribution history, but the repository is no longer actively maintained. Because automating Discord user accounts violates Discord’s Terms of Service and can lead to account penalties, this project should be treated as a risky proof-of-concept or research library. ...

There are still a few smaller inconsistencies, however. For example the web client sends lots of telemetry...
