its the best solution ive found still
You posted here long ago. Did you not try my solution, or did it not work?
That firefox addon fetches pages in a hidden iframe. That's why it's so slow. I consider this type of mass fetching a potential ddos risk.
Try that userscript with the tag filtering on the homepage. I talk about itch.io. This page has those # tags. Maybe they are on jam pages or elsewhere too. And I guess it would filter the main genre.
Anyway, as I said above,
I made a tampermonkey script to do this on the press of a button.
This being the client side css blocking of individual games and all games by selected developers.
You cant't block tags client side on the browse pages, because that information is not loaded on that page. The only info loaded is the main genre (and I made a script for that too ;-)
You can even use my userscript to emulate multiple tag exclusion, if you bother to set it up. Just positive search for what you want to exclude, have endless scroll active and scroll down a few hundred games and up again and then hold the 1 key. Do that again every few weeks, or just add individual games as needed.
Adding games individually to your show-me-not list is the better strategy anyway in my opinion. This thread was about creators. To igore these with the script, show a game of that dev in browse, hover mouse over game, press 3.
The idea originally was to hide your library from browsing results. But the mechanic can be applied to things you do not want to see too.

I have no screenshot for the script, but it's on my project page too. And it has some basic bells and whistles. You have two different lists, export and import functions. The configuration is bare bone and at the script header.
