In meatspace, underground zines wouldn't be in Barnes & Nobel, they'd be in the independent book store or record shop. Mainstream shops never let just any material be sold (especially when they were leading the market compared to Amazon). So, is content really "underground" if it's on a social media site like Tumbler, FB/IG, etc.? "Underground" implies distribution via alternative channels, and in 2022, webrings are alternative (compared to mainstream social media sites).
