If she was one of the posters disguised, it would be very nosy and an invasion of someones elses propperty. We post what we feel and want to say in here because we trust the people who read it, to act like they really are. If anyone was in here acting like something there not, I think that would be really low class and uncivlized, not to mention extremly dumb. \
If an older person was listening to teens and kids convo's,and faking their personality, then I think its really wrong of them. Usernames are okay, cause they just sort of give you a name you wish you had!LOL!
I doubt JK would do that anyway. If she's out in the world of fame and fortune, she would know what it's like.
