Having a fake open 22 is actually a great way to build up a blocklist.
It was particularly fun to watch young people who were new to the scene sort of freak out at this weird architecture. Old farts were easy to spot, they would start right away with a 'show dev' or 'set host' to try to move around the network. Kind of like a hacker aquarium.
Kudos for having multiple vaxes(n?)!
