Hey. I'll take it on, at least temporarily. I have experience as a mod for a mid-sized city community on Reddit, and am working on building the equivalent community here.
Yes. The original owner joined, registered a few communities and then never returned. So we purged the inactive communities but those that are active are now available to other people who wish to moderate these communities.
I wonder what they did. The rules are basically "don't be a bigoted jerk, a troll, or a spammer." Those aren't difficult rules to live by (though some people do have trouble in that area anyway).
I can also help out. I don't have much moderation experience but I can check new posts a few times a day and check reported posts. I definitely won't be able to carry a large community but can help out at least until we find permanent mods.
