Yeah, I get that you feel like it is annoying and beating of a dead horse. But if shitty people are not held accountable for their actions, then people will "forget" that and they can continue to be shitty just because people aren't talking about it anymore. Also, new people who are completely unaware of the character of said musicians going through this post (and previous posts) will find out that he really is a shitty person and learn of the true situation. These artists constantly being ripped on for being shitty people should ideally, make them want to be better people and make right their wrongs in whatever way they can in order to prove that they aren't shitty people, just someone who made a mistake and wants to fix that (but that is not how life works sadly). If they don't want to try to fix and change for the better, then they deserve to be berated. This constant reminder should make them feel that they are doing something that is inherently wrong, otherwise if people were to stop doing so, then they're no longer necessarily being held accountable for their actions and continue to behave however they please.
Note that everyone needs to be held accountable for their own actions, not just shitty people.
And if people don't want to listen to the music, then so be it. No need to be GTFO like you're on some special pedestal here listening to your Miss Fortune. You can like them, but that is unnecessary to say it like that.
