It'd be a lot harder to call out a Performance macro as "botting." This is kinda a special situation of not really being a gameplay mechanic. As long as you're not going afk while spamming the same song or whatever, what's to even call out?

Further, as long as you don't shout that you're using an outside program to macro the performance, there's literally nothing to take action on. Players can suspect "oh that was played really well/perfectly, they must be using a macro editor," but, there's no evidence of that, so, reports would go nowhere.
