Why book bloggers use pseudonyms

Last January, I read NO ONE ELSE CAN HAVE YOU and thought it was a funny little mystery, just falling onto the right side of the twee line.  Yesterday, author Kathleen Hale published a piece for the Guardian, "Am I being catfished?" that reveals that a) she has no idea what catfishing is and b) stalked a book blogger without realizing she was doing anything wrong.

It is a horrifying article.  She finds the woman's address and work address.  I sometimes consider just going by my real name here, since it is a bit of an open secret.  But then I read this.

So yes authors, many of the book bloggers you interact with are using fake names.  Maybe lying about their personal details to muddy the waters.  Obviously, this is one incident with one disturbed person.  (See another article by Hale where she throws hydrogen peroxide in a girl's face and stalks her for two years and yet still makes herself out to be the victim.  Wow.)  Still, I think I'll keep my pseudonym. 

Also, kudos to HarperTeen for backing away from this mess.
