running it democratically is kinda nonsensical, ultimately whoever wants to put effort into maintaining the community makes the rules. process to get on to modding is pretty easy, if you want more say then you should put in more effort.
you cant run a site like its a political entity. its all on volunteer basis. the only thing you can really do is make sure you prune mod lists whenever someone does something reactionary (or make sure mod spots are only given to long time users). if this were run by a party, then you could easily manage the site through bylaws, but that isnt how things work here, it isnt tied to meatspace.
