This is Mr Bennett's quote about her myspace page:

What kind of posted text/photos(?) would have caused him to change her password? My personal interpretation was that they were of a mature nature (couldn't think of another plausible reason), and he was uncomfortable with it.
Of course I could be wrong!
We don't allow our teens to use myspace yet (don't know if we will ever), but if/when they are on there, vulgarity/swearing/fighting would be reasons they would lose the privilege.
