Something else just occurred to me, you might try the Dungeon Crawler Carl series by Matt Dinniman or This Quest is Broken series by J.P. Valentine too. They are a newer genre called LitRPG where the conventions of gaming (like things being “quests” or health/mana bars are directly apparent to the characters and it makes for some interesting moments.
I don’t read a bunch of strict Horror, but I have enjoyed the ones I’ve read by Grady Hendrix.
Otherwise, based on your answer, here are a few books I’ve read that line up for one reason or another. I’ve placed them in a specific order but they are all enjoyable:
Kaiju Preservation Society by John ScalziJohn Dies at the End by David WongDark Matter by Blake CrouchThe 7½ Deaths of Evelyn Hardcastle by Stuart TurtonThis is How You Lose the Time War by Amal El-Mohtar and Max GladstoneHow to Live Safely in a Science Fictional Universe by Charles YuEcho Wife by Sarah Gailey
That was my take too. Their overall point wasn’t bad but the start was a complete non sequitur that made me question if I wanted to finish because it’s a bad foundation for their actual argument. 
In Japan, there’s a competition known as the Kezuroukai Planing Competition. It’s a challenge for experienced woodworkers to see who can plane the thinnest contiguous piece of wood using a type of hand plane known as a kanna. The thinnest piece I last heard of was around 3 microns.
I only mentioned this because it sounds like your skin might beat the record if people calling out the bad behavior of others on your instance immediately gets you this riled up.
People don’t want to block hexbear because they disagree with them, they want to block that instance because they often act like they’ve got the social skills of a neglected 5-year-old on meth. Further, because that’s who they’ve surrounded themselves with they have convinced themselves it’s normal or even appreciated.
They shouldn’t have had storage issues, they were never going to host images or communities. They simply were an instance that only federated with nsfw instances so all could be only porn.
