so if you have to have a G+ account (for YouTube, location services, or other reasons) - here's how you can make it totally private! No one will be able to add you, send you spammy links, or otherwise annoy you.
You need to visit the "Audience Settings" page - https://plus.google.com/u/0/settings/audience
You can then set a "custom audience" - usually you would use this to restrict your account to people from a specific geographic location, or within a specific age range. In this case, we're going to choose a custom audience of "No-one"
Check the box and hit save. Now, when people try to visit your Google+ profile - they'll see this "restricted" message.
You can visit my G+ Profile if you want to see this working. (https://plus.google.com/114725651137252000986)
