On Self-Moderation and Moderation If you feel like the posts from a user are totally irrelevant to you, you might have no other option than simply block them temporarily by visiting their profile, and there is an option to block the profile (to unblock, there is a list of blocked people: https://plus.google.com/apps/activities/blocked_users ) -- it works, and will keep signal-to-noise ratio high. And, regarding moderation -- let's discuss criteria ( https://plus.google.com/112297796445914390564/posts/NheFcE9Dfrd ), let us know who would like to contribute the moderation. I would definitely love to contribute. (Posting from my auxiliary account, so that the blocked ones can also notice.)
