It's surprising how many commenters are doing exactly what you say that you hate!
I've also started to prune the people I follow. Due to plankton anxiety disorder, I followed as many people as I could in the beginning of my Steemit journey. I came to realise that most of them were dead accounts. Many of them also created content that I could not relate to and just jammed up my Feed.
I guess this is part of the housekeeping that we need to do.
