The famous Stanford Prison experiment has numerous methodological flaws[0] and is most likely hokum, and Phil Zimbardo, the director of this study has exhibited numerous moments of questionable ethics. Including sleeping with and marrying one of his research students.

Right or wrong as a moral or professional practice, this was incredibly common in the 20th Century, and if that implicated bad science, we'd have to discard quite a lot of it.
Also, it's hard to see how sleeping together would cause them to do bad science.
