The media will cover any story they think will sell, and unfortunately, the majority of the public do want to know these things. Some of them will stalk/aggravate these people themselves if they don't think the media is covering them well enough. Some just want someone to hate or love, or they want a scapegoat to pin bad behavior on, so they react and encourage the media. They don't care about the person's feelings, just that they will be able to put the story out and earn money. That's just an unfortunate reality of being famous.
