Communities usually named 195 or 196 have a rule that if you go there you have to post something. So people will post something and title it "Rule." And it leads to a bunch of low effort crap posts.
Just block any 195 and 196 communites to save your feed from getting overwhelmed with bad posts.
Mostly rock. Specifically love 80s hair metal and hard rock, and prog rock/metal. Lately I've had Sleep Token albums on constant rotation.
