As someone involved in education, AI has been a hot topic. I have a pragmatic view that AI, for good or bad, is ubiquitous in our society so it is better to control how it is expressed in the forums where you can set explicit guidelines and consequences for abuse rather than ban it entirely and have it go underground. I would advocate creating a dedicated subforum for AI music and be clear that AI music must be declared as such can only be submitted/discussed there and a clear policy that violating these guidelines can lead to suspension or banning from the site.
Also in the end, if someone wants to pass of AI music (or any other creative endeavor as their own), it's really hurting them more so than others. They are not improving their creative process so any praise/feedback is hollow and meaningless. At least it's not stealing someone else's work and passing it off as your own (which has happened to me). I am of the mind that AI generated art in all forms will always be inferior to human efforts so in the end who really cares?. If AI every got to the point there were really think it is on par or superior to human effort, well, then great since a masterpiece is a masterpiece (I am just doubtful that AI will ever be able to achieve this).
