I got this SteamBot in NodeJS. It's a nice new bot, created from scratch, which can be used for automatic trade accepts. You have to modify it yourself but it's ready to use and to test. It's well documentated and you should find the functions you have to edit to make it 'a real bot'.
The bot is made by Jake 'rannmann' Forrester and I got it from His NodeJS Bot Tutorial
I edited the code and built a 'multi-admin-system' where you can insert multiple admin SteamIDs into an array and a simple command system with a basic !help command implemented.
How to use:
A bot account for your steambot with at least $10 purchases.
Npm and node installed.
Download from Mediafire:
Run 'npm install' inside the directory.
Edit the config.js file.
Run 'node server.js' to start the bot.
Look at your Steam-Guard-Code (from app, email or sms), type it into the cmd and press return.
Now your bot is running and should be shown as online in your steam-friends-list.
Test it by writing him or sending him the !help command.
