I'm not sure. I enabled G+ to manage our business page, which made my account visible. The couple of people who found it added my personal account from knowing my email. I circled them mistakenly (a slip of the mouse is all that's needed) and then uncircled them. They get a notification that I am, indeed, on G+ and am now ignoring them. Knowing this beforehand I would have made a new email address to manage the account, and could freely allow circling. I guess I'll go find out now if I can change the owner of the page.
