Yes, it happens. But it comes with the territory. You will be rejected as a writer, you will be criticized. And not everyone will love what you write. You do what makes you happy, put out what makes you feel good, and hope that others will enjoy it as much as you enjoyed creating and sharing it.
I don't change it. Sometimes I will find grammatical errors and fix that but I won't do it to appease anyone or to get my traffic up. I write it because I believe in my own stuff. What others think is their own opinion and they are entitled to it, just as I am entitled to mine. I thank them for it, whether it's positive or negative praise and move on to my next piece. Deleting something I wrote is not an option.
