Yes, but those are for commands being run. Nightbot has no triggers for a) when someone follows b) multiple streams of followers c) triggering songs to run directly from commands like you suggest. You can effect the play queue, that’s about it, you can’t do the kind of complexity that you want.
It sounds like you really want a custom bot/program, that kind of complexity is not going to just be ‘available’, you can likely find many bots that do some of what you want, but not everything.
I might end up with streamlabs (formerly ankhbot) because I can write python and it can take custom scripts. Just trying to avoid that if I could find a bot with some of the available triggers and piece together some logic. But you’re right, there may not be any avoiding it. Thanks!
