Aww, a Discord would be dope to retain a fanbase and be a part of. I really think you should look into it, worst case scenario you could have mods that moderate it for you and you just announce things there as well. Also, I don't think *donations* towards a project even with copyrighted content is any more illegal than the current state of it, but to play it 100% safe the donations can be simply to you as a developer (such as through Ko-Fi). That would make it irrelevant to the project.
