Verified this myself. If I add a firewall rule to drop traffic to cache1.primal.net then Primal fails to load posts. This isn’t decentralized and would make it very easy to block Primal at an ISP level either by blocking DNS lookups for cache1.primal.net or blackholing the IP(s) it resolves to. nostr:note1apxc6nq35wn6lx59gewzgvtrwcv20u9njz38racuxw4mtm4vfnksnj92l3
