If he legitimately had the money, this thing is icky, but not all THAT icky. That is about as worked up I can get without knowing more about the situation 25 years ago and what has happened since, regarding him and women to which he is not married.
What would I do if my 40 year old daughter told me she willingly shared a naked hottup dip with a 30 year old 25 years earlier, that the guy has apparently behaved well since, and that he had recently paid her 150k to keep quiet?
I'm not certain I could work up enough indignation to want to ruin his career.
