I have maybe a DOZEN(give or take) specific tags pertaining to things that I really just don't want to see, such as cock_vore, for instance.
The problem I'm having isn't running out of content I just don't like seeing, it's particular art styles and artists. A MAJORITY of my blacklist is filled with artists and I've run out of room.
MANY of the artists I blacklist all use a similar style of art that don't have a specific tag, which would cover their art without filling my blacklist with JUST artists.
I'm not saying the art is bad, I'm saying it would be nice to have umbrella tags for art styles for exactly that reason; to keep a blacklist from overflowing with artists who all share a style of art. Trying to tag some of these artists has even caused my blacklist to stop working ENTIRELY and I've had to revert to using a text document of tags as a backup of what tags WORK to keep my blacklist functional.
EDITED: Some artist tags don't even work at all. Blacklisting them does literally nothing to hide their content from my feed, meanwhile other items I've blacklisted are being hidden.
I don't know EXACTLY how to describe it without simply calling out an artist as an example for an umbrella tagging system. I mean, we have a tag for 'manga' which covers a BROAD range of art but doesn't always cover JUST manga-comics but also covers singular images.
