I don't doubt that Jana is exactly as she is portrayed rather quiet, but this is fundie land and what constitutes as poor behaviour is different to a normal persons.I never heard this about Jana at all? Any inside sources have always said she's as meek and mild as she comes across.
I can't quite recall the exact details, but I might have been in one of Michelle's books and then at some point it was vaguely mentioned she also went to one of these camps but dressed up in a positive way which was weird as we know that unofficially these were punishment camps for the fundies/IBLP lot.
Now I know and have seen photos of all the girls at various camps which muddies the waters but there was some convincing gossip a few years back that Jana had also been sent to one of the 'bad kids' camp.
