Not even a linux guy, but I had a Pi from a decade ago that I never opened, decided to set it up and use it for something useful, friends suggested Pihole. pained myself for 2 days getting everything working (most of my trouble had to do with peripherals and IP addresses not the device itself) but after the grief, got it working and it was well worth it.

I even printed a sticker for it that said “where ads go to die”

sorry doubleclick, but you’re toast
