Let me add that I believe that Percy is working for the Order as a 
spy at the Ministry, and has not betrayed his family.  

Kemper now:
Others have responded to how everyone in school found out with the

I, too, wanted Percy to be a spy and had thought he was when I first 
read OoP.  But no.  In an interview...

... JKR was asked by Echo: "Was Percy acting entirely of his own 
accord in Order of the Phoenix?"  JK Rowling replied, "I'm afraid so."
