Original V1 Java source is not available and never will be (mostly because it's garbage).
Feel free to run this bot in your own guilds. Be aware that most all of the IDs are hard-coded and will require changing.
Any change you make you are responsible for. I will not provide support for this bot like I do with Volte, as Volte is my main, general-use bot and this one is specifically for one Discord guild. I will also not be making releases. The bot will basically stay at V2.0.0.0 until V3 is released, if I ever release another version.
Despite this, you can run this for yourself and have fun. Just be aware that you're on your own.
