And then I clicked on an unfamiliar follower. The little picture-gizmo said "Help" and I thought that was an odd name for a blog. So I went there and boy was I surprised! It was somebody asking for money! Just asking for hand-outs! In about 27 different languages, no less!
I felt used. I felt invaded. I felt peeved. Really peeved.
So I found out how to block a Follower and -- there, take that! -- blocked this person.
