Keep connecting with other people in Google+ -- and keep more spam out with our new content controls setting.
Our Communities are great places to share and discuss the things you love. Unfortunately, spammers are also aware of how communities bring lots of people together, and they target all manner of spam or racy and inappropriate content to many of our most active communities.
So today we’ve added more protection to our communities with stronger content filters & controls. Now we can be more aggressive in identifying inappropriate posts in a Community. When this setting is on, Google+'s content filter is more likely to flag posts that are questionable, so fewer of them will show up in your Community. Check your moderator queue to see these blocked posts.
Stronger content filtering will be on by default when you create a community and will be gradually enabled for many existing communities, so we can keep your communities great!
