I do think creatives should listen to overwhelming/trending feedback from audiences so they're not totally tone deaf and can write to what's actually resonating with audiences - and if something isn't working with the audience, they need to strategize how they're going to fix it.
That said, in the social media age, there's always going to be "haters" or a group of people that bombard with negative sentiment over and over again. If you're going to keep your profile open to the public, that is the price you have to pay. MVJ needs to learn to not take any of this personally, tune out the unnecessary noise, and take everything with a grain of salt. Defensive social media posts like that will only give attention to the people who she wishes would stop, and frankly, does not come off as being confident in her own work.
