DADA textbook prop?

[snapesmate]

Phooey!  LOL!  I just don't get it...  According to "Fantastic Beasts 
and Where to Find Them" by Newt Scamander (JKR) humans only turn into 
werewolves when bitten, there is NO cure, that werewolves, unlike 
other "fantastic creatures", actively seek humans in preference to 
other forms of prey, and that at any time OTHER than a full moon, 
wizards AND MUGGLES afflicted are perfectly sane and normal!  So the 
alleged prop DADA textbook content:  
http://hp4unews.blogspot.com/2004_02_01_hp4unews_archive.html#10762697
5420360745  is bunk as related to JKR's werewolves!!  So why did they 
use this content copied from a the adventure game "A Gabriel Knight 
Mystery: The Beast Within"(circa 1995)?? This was written by the 
creators of the game, as directly related to the game.
