I really can't say if he did molest a bunch of people in the past or present. If I had to hazard a guess, I would be inclined to say that he did.
Also, IMO A LOT of these 30 year old #metoo style claims are pretty much after the fact witch hunting. Yes, many are true, but others are merely unwanted flirting/courting/creepy behavior/regret sex. And to bring stuff up decades later - to get your 2 seconds in the spotlight, because the other party is famous, because you regret your actions in a quid pro quo situation is quite lame and just bandwaggoning. Right now, society is dangerously crossing the line from legitimate claims that should be prosecuted (if true and with sufficient evidence, and within statute of limitations) to people just throwing shit at the wall and seeing what sticks.
