I take the stance that the less moderation the better. Keep out spam, keep out obvious abuse, but there should never be the sort of moderation that turned the subreddit into a joke. No policing of language. No punishing for posts that occur in other parts of the fediverse but not directly in the Portland group.
Definitely no locking or removing threads because "too many complaints, too hard to moderate." Oh, your volunteer job is too hard? Time to find a new job.
