What do you think of the use of spying, spy characters, and other such things?
Spying is always bad.
Spying is only bad if it is done via OOC channels. (i.e. getting a friend to join the game so he can spy for you, or passing messages via OOG methods, etc.)
Spying is only bad if people specifically create a character to spy on a realm, or move a second character to that realm to spy on them.
Spying is fine, if existing characters have good IC reasons for it.
