A certain Etsy seller.
I purchased a wire work tutorial from an Etsy seller. I have done wire weaving and crochet for a long time and I am quite good at it. When I came across a tutorial for a technique that the seller described as new and innovative, that they had developed themselves, I was curious and bought it (it was not inexpensive for a tutorial). Guess what? It was the same old technique, under a new, fancy name. I waited a few days to cool down and posted a two star review, saying this and citing sources for the technique.
Today, I get a message for the seller, asking how could I leave negative feedback. It has a big impact on her business and she took a lot of time making that tutorial. In other words, it was all about her and her business, not my satisfaction as a client with her misrepresented product.
You know what? I don't care. If she had phrased it differently, I might have considered the refund she offered as though it were a big favour. But to remove a negative but accurate feedback because it could hurt her? Guess what? It would hurt because it is true!
