What area of New Blood are you suggesting this for? Zombie Survival
What is your suggestion and how will it work? My suggestion is that, players who are afk for a long time will go into spectator mode, and can type /join at any time possible. Players should also be able to go into spectator mode by choice by typing /spectate They can also simply leave spectator mode by rejoining.
And this is an actual genuine spectator mode, unlike the one already implemented. Players in spectate mode will be able to fly around and noclip, while being invisible. It works on CTF so it should be able to work here.
What are the advantages of your suggestion? If we are able to actually spectate, it create a lot of opportunities for recording gameplay and even making trailers as it offers a lot of unique camera angles instead of the boring typical first person videos. New Blood could get it's own trailer made by different people and in general I think it would give people a better idea of how zombie survival works.
What are the disadvantages of your suggestion? There are little to no disadvantages in my opinion. One could say this would be difficult to code, or some newer players, or players with a language barrier would not be able to know how to join.
This has already been suggested and is currently being discussed via Discord!
Arguments for both sides have been discussed, although

This is a nice pro for /spectate that I don't think has been mentioned on the Discord suggestion!
Major reason why this has not been implemented is because it will easily exploit secrets on maps and players in theory could pm zombies in-game exposing specific human locations.
