If I was the instance admin, I would only consider putting you as a moderator after you had been active for long enough to show that you're already doing more work than the sleeper mod.

As for removing them, I probably wouldn't unless they had done something to show they weren't trustworthy.

But as it stands, we still need our communities to be built up and that will take effort from active participants.

Over the next few weeks Reddit users will be filtering in and out like a party and will be scanning the room, we need activity to already be here and that will have to come from us participating more than we normally would have on Reddit.

Earn a mod spot before you ask for it.

I think it's an admin thing. They'd have to remove the inactive mods and instate you.
