I’m looking to find a place where to post an advert for my online fake country

so recently I’ve been trying to form a sort of fake country where people can try and simulate the politics of the country and initially I did it between friends but it didn’t work out because of some problems, and now I’m looking to try and start while on discord, but I wouldn’t know where to post something like this on Reddit because I can’t find any subreddits to post this so I would be thankful if someone could find one.
