Seen the documentary now, still think they're just scammers hoping to get a payout from his estate or something.
At the end of the day, and this may sound very insensitive, we know he was close friends with Elijah Wood and Macaulay Culkin (other child stars which he shared common ground with) and he never touched them, or any other of his child star friends. The only ones accusing him ofowing them moneymolesting them are ugly poor people.
Now you can say that all his alleged victims being poor is just coincidence, but as the entire case against him is circumstantial and has no real evidence baring the word of people who have previously defended him ("we're not lying now but we were lying before but we're not liars, give us money!"), I think it's safe to say it's something we will never know for sure, but as weird as he was the evidence is still on his side.
Basically, the criminal cases (accused and or taken to court by the police) he fought and won, his accusers proven to be lying. The civil cases (people suing him) he just settled out of court because he could afford to pay the gold diggers to go away.
Its too easy to write it off as money, and there are many examples of why money isn't a motivator for them coming forward, i.e. not monetizing the film, keeping hold of rings worth tens of thousands etc etc..
