I guess there is a question about how well moderated a community is if no one checks in for 5 days.
This is exactly where the 5 days comes from.
The issue we're facing is there are some active communities that are getting reports where the current moderators are not active, not dealing with reports, and not responding to communication from admins.
While it's workable on a small scale, as admins we shouldn't be defacto relief moderators, and really shouldn't be enforcing any community specific rules.
Unfortunately it's a bigger problem than you'd imagine it is. There are numerous fairly active committed that are essentially unmoderated at this point
