I really hope their has been additions to Kate's story. It can absolutely be smoothed out, but there is a decent foundation. She is a side-character, but so much fun potential. I absolutely got attached and wanted more. Im going to wait for .21 rather than .20. The former should have story updates.
Outside of that, I can't disagree with you much. Mind you, content like this will attract more unsavory types than normal content. Calling them out and sticking up for others is always a good thing in my book, just dont let it wear down on your mental, cause i know it wears me down!!! Haha.
