Don't worry about a thing. Over the years I've come to appreciate feedback in any shape, way or form. Anyone taking the time to reflect on my product, my work or me as a person is someone who's apparently invested, but possibly didn't get the exact thing they were hoping for. I can only listen and learn from this.

It might also help that I'm Dutch and we're supposedly pretty "direct" by default. I've also learned from dealing with Russian players who are even more versed at that craft.
