Cause and effect. If something was deemed as too far, then we'd just discuss it and resolve it. We'd then write the story over some sort of instant messenger.
The way the setting gets made is simple enough. Basically, someone comes up with a concept("hey, you know that existing Reverse PMD concept we have from another roleplay? What if we placed it in colonial Australia?") and then we just fill in the gaps of what we need from there. If you think it is what you want, then you just throw it into the pot.
One way to coordinate it, if we wanted to, is how we approached many of our trainer roleplays. We'd come up with a gym setup to roll through, and then we'd take turns as the gym leader. Whoever had the gym leader also was in charge with coming up with the town and its various locations to use within that town.
It's very fast and loose, with few rules, and that's what I like about it.
In recent years, I've wanted to get into TTRPGs, but I can't work up the courage, so instead I'll bring in things like coin flips to simulate having dice rolls. I hope to one day to do a system like Shadowrun or something.
