I’d also be happy to chip in. East coast US; I modded r/lostarkgame for several months around the time that game launched in the West.
Philosophically, I think it’s a matter of what you want the community to be, and there are some decisions to make on that front–things like, do you want to curate news for the game, or do you want to be a lounge for memes? a little of both? Laissez-faire moderation works for a small community, but it gets harder and harder as the community grows. More robust rules get you a little of the way, but ultimately a lot comes down to even-handedly enforcing the current rule 2.
