Every newbie who has uses Google+ has at one point been concerned getting notifications alerting them to an unknown person has placed them in their Circle. This has freaked out a number of Facebooker and LinkedIn’ers to not end. I know a few who will not use G+ because of this.
Don’t Freak Out!!
The truth is, having someone circle does not harm. Circling on Google+ is not like “friending” on Facebook, which is a two-way relationship.
The most common concern most people have is that unknown person might be able to see your private information. Bottomline: They cannot.
A person who adds you to their circles can only see information that you share with Public or possibly with Extended circles…meaning if that unknown person is in the circles of someone in your circles.
People who add you cannot see posts or anything else shared only with your Circles unless, of course, you add them to your Circles.
Another huge concern many Plussers have with Unknown People putting them in their circle is that they might be able to spam your Stream.
That is near impossible, but can happen. Most Spam comes from them putting you in a Circle and then Posting Crap to just that Circle….Google Needs to tighten that up, but will be hard to do. So, Spam will come..just keep blocking it so Google and cut those people off.
Interesting enough, having you in one of their circles allows people to attempt to share posts with you but the posts will not appear in your Stream unless you add them to your circles.
That being said, some people simply do not want to be in specific people’s circles for one reason or another.
If that is the case..here is the Fix…You can remove yourself from a person’s circles by blocking them.
Blocking can cause complications, however, the trick is to block the person and then immediately unblock them. (Unblocking does not add you back to their circles.) Using this trick would not prevent them from circling you again, but the odds are excellent that they won’t notice that you are no longer in their circles.
If you have further concerns about your privacy on Google+, give a shout, I’ll see if I can help.
