I am annoyed everyday. Unknown people are adding me to their circles. How to allow only the people in my 'Extended Circles' to add me to their circles?
How to control who add me in their circles in Google+?
google plus
You can't stop people from adding you. If you don't post public you have nothing to worry about, they will never see a thing. If you post public even people who have not added you to their circle will see the post if they visit your profile. Even people who have not joined Google+ will see it. Public really means anyone.So either way you have nothing to worry about people adding you to their circles. It makes no difference at all.
