I see the categories like this:

1. This is the category of Heffner and Epstein. They had their own desires but their main job was to get kompromat on important people.

2. This is for the Weinsteins of this world. People who do it because they can. They wield sufficient influence and power to get away with anything.

3. This is for the P Diddys and other top movie and music stars. They had to become compliant to get where they are and some took the "if you can't beat them, join them," approach.
