So interesting to read the various posts on this topic. With Gary Glitter, Ian Watkins and the like it's been found in a court of law that they were guilty of the crimes. With others (MJ, and it would appear, a smorgasbord of 60s and 70s rock favourites) either dead or uncharged it's down to a moral call which will be swayed by your own judgement on that person's character, music, haircut or some other triviality. Certainly a moral minefield.
