Unless it is a fake account, "Bishop Luis Antonio G Tagle" signed up to me as a Follower on Google+.

At any rate, fake or not, I sent him a Hangout message as follows: "Is this really you? If it is, know that I was your Psychology teacher when you were a college freshman."

That should give him or others something to think about, fake or not.

P.S. I really was his Psychology teacher when he was a college freshman.
