The minimum advertising window time length is 24 hours.
That would be fine if people stay in your game and you have a large enough budget. You could also be a staff for a few hours so people can do stuff
Yeah, but to retain a player count I’d need at least 1 staff member working 24/7
You could see who can be trusted when you are on and get your friends or family to help
I don’t have much family or friends, but there’s a resume process.
There is a resume process for what?
For becoming a staff member in the game.
I don’t know what you mean when you say resume but you could have a game pass to become staff and a vote kick feature
Ok sorry I am from England, you could give staff to the first few people on a server for just that visit to get you started
Staff have the power to trap and kill players. Unfortunately, this is not a practical option.
Not even with vote kick or you could not have those permissions on those players
Staff can’t kick, only mods can.
Make script so staff can be vote kicked
That could easily be abused, plus this is no longer even related to my original question. Thanks for your feedback, though.
Why not have a round-based scenario where players are randomly assigned to the position of staff/villager/cursed, and then after a few day/night cycles, the roles are randomly swapped again. As the game currently stands, it doesn’t sound like this would be feasible, but if you are willing to give up some of the staff’s powers in exchange for a game that wouldn’t rely completely on having trusted members of the staff (and even if they do abuse, their roles will switch at some point during the game), then I’d say this is the best bet.
Staff are basically mods - they have the power to ruin the game or make it fun - it would be too risky to give random players the ability to make announcements, stun/kill other players and give them low-level mod tools. I want to keep it not as a round based system, similar to the TSO games. Thanks for the feedback, though! : D
I’m no workforce manager, but from my perspective there’s 2 methods to solve your manpower problem: optimise or expand.
Firstly, optimisation. There’s sure to be more than one way of achieving this, but essentially it involves optimising the role of staff. One way if doing this that’s been previously mentioned is replacing human staff with scripted events and AI to fill their place in the game loop. Alternatively, you could try optimising your hiring process: is there a better way of hiring and screening staff than your current one? Have you considered advertising staff placements within the game itself to attract more of your playerbase towards become staff members? Perhaps you can lower the requirements to become a staff member and instead focus on training staff who might be under the bar as it were?
Secondly, expansion. Like you may have mentioned earlier, if you don’t have enough staff then it makes sense to expand your staff team. In your so called ‘chicken & egg’ paradox, you’re having difficulty attracting staff because of a lack of staff. It’s quite the canundrum. I touched on this a little, but are there steps you can take to advertise the need for staff? When players are on and staff aren’t, is there some sort of notification that explains the need for a staff member and that encourages them to become staff? Can existing staff help advertise in any way? Advertising the game might help by expanding your playerbase, but can you include an advertisement for staff placements as part of the game advertisement? It might attract people purely for the need of staff.
Sadly the most we can do is provide suggestions that may or may not help, it’s your game and only you can decide how you want it to work and what you want to do with it. I don’t think there’s a single magical solution to the underlying issue that staff are required for the game to function, so it’s going to take some time, trial and error. I hope you can solve this issue for your game and playerbase’s sake, let us know how things go! 
And if you do find a magic solution, share for anyone else that might find it useful 
why not create a game script that runs everything instead of a human running commands?
Just Advertise a lot (30K+ per day), and you’ll get loads of staffs and members.
Chicken or egg? You’ll need a farm anyways.
Yes, use AI when you can instead of manpower.
You can still make AI Staff such as Siri with some in-game functions and chatting feature. Would take some time to make, however.
