I tend to believe with that much smoke there is fire, but as an ex-twink I would have been thrilled to be sexually harassed by a famous actor like Spacey. Obviously wrong if it gets too rapey, but I'm thinking for all the complainers there must have been many more who were flattered.
Of course this kind of thing gets dark when the pursued are fooled into believing the successful person can help them with their careers when they have no such intention, and I personally know someone like that who exploited his success shamelessly that way, but as long as we are talking about adults ... what's the biggie?
