My username came from song lyrics, and I don't use it anywhere else.

If I search my real name (and I do, occasionally) a paper and presentation from my undergrad pops up, along with academic awards. However, when I searched it 2-3 years ago, I came across a blog written by one of my ex-friends who had trashed me & put my full name of her blog, along with my location. I notified the host of the blog & they took her entire blog down.
