I actually already have the code for this, the forwarding of messages, including content, files, embeds, the selfbot, the ability to have it output it via your personal account, or a bot account, and it's built in node.js. All I would need are the channel ids, or you could input them yourself in the config file. I also can make it so you can start the bot up by clicking an icon, just like any other app, and even have it auto start when you boot your computer.
