Perhaps you filled a niche? Fix it fics is a genre over there and a few have done well. A lot of them probably at least share some of the critiques you do as they probably were the second most nitpickish of the final besides /mlp/ when I briefly checked there (though still more positive overall).

This. Though I consider my endpone stuff to be nothing special it is vastly superior to my first attempts  that date from 2011 and 2012.

Hmmmmmmmmmmmmmmmmmmmm... All the rules in the screencap seem familiar to me other than the no chapter updates announcing a sequel. I used to see fanfic authors do that all the time with squeals and non story updates. I've been pretty outta tune with the site over the past three years but I have seem them allow experimental stuff fairly often in old times. Including a fic that was just a picture with text in a multitude of colors and a variety of formatting even with those rules in place. I'll have ta go back and see if they are still there if I can remember them.
