My solution for this type of situation is MicroBin running on my home network from a non-standard port, with a port knocker to open and close the port when needed.
My router handle DDNS so I can always contact my home network easily. I port-knock to trigger an iptables command on the router to forward traffic to the MicroBin host.
I also have my phone set up to connect via openvpn to my home network so that I can remotely do things like start and stop services, set port forwarding rules, etc.
Because there is value in a large group speaking with a unified voice to say “this is wrong, and you need to know that the rest of us think it’s wrong. Your behavior will affect the relationship you have with us all going forward”. Direct intervention isn’t the only form of consequence.
Is it the best solution to the problem? No. Is it still worth doing? Yes.
