Just catching up here. I find her comments bizarre - particularly the one about people trying to ruin her 'business' by contacting brands she works with. That's not about anyone trying to ruin your business, that's about accountability & professionalism - case in point when she was misusing the retinol product. In all likelihood, consumers (her audience/followers) will give feedback both positive and negative to brands she works with based on how she recommends, styles, and endorses particular products.
The fact that she couches it as a personal attack instead of an opportunity to realize that maybe she needs to improve or up her game when it comes to the products she is endorsing pretty much says it all. Anyone who is a professional, regardless of what field they are in, can expect to face a review period or some negative feedback at some stage. That is the nature of working life. As is professional accountability. Review periods/ criticism/ feedback provide the blueprint for the next steps you need to take to move forward and grow.
Why shouldn't consumers contact a brand she is misrepresenting to raise their concerns & expect it to be improved upon next time? It's baffling that she doesn't understand that.
When you behave like a glorified QVC salesperson and flog every and any product going, without a clear aesthetic or theme across such a wide spectrum, of course you are going to fall short. That is not on the consumer/follower, that is on her.
