Google+ used to be my refuge from spam followers but I'm seeing a strange inversion: More traffic from people I know and work with on Facebook, and a flood of spam followers on Google+.
What does the phrase "spam follower" even mean? Where relationships are reciprocal (e.g., where "follower" also means, at least by default, "invited sender" -- as in the case with Facebook friends) I guess its somewhat meaningful, but where following someone's output is independent of your output being sent to them, how can a "follower" be "spam"?
