Well, one possible reason is: in hope of money.
The accusations may be true, but they may as well be totally fabricated. There are people in the world who want to get rich easily, and what better way to do it than to sue a rich weirdo of which many can easily believe he's a child molester. (Shouldn't be that hard if you look at all that's been written about the guy.) And look at him, doesn't he look a bit freaky? Must be a child molester....
