I think the main intention here is to block the bots. Reddit blocks requests coming from certain IPs associated with VPS and similar commercial providers. VPN services often rent exit servers there. My connection is blocked when it goes through Tailscale exit node hosted on a VPS.
You can use Tor to browse Reddit anonymously, there is even a .onion address



I’m running one Pi-hole, but not on RPi. One is an LXC container on my Proxmox host, another is on dedicated Dell Wyse thin client box.
