Can women view the profiles of all men, regardless of their membership class?

As with an app, women generally can’t view men’s profiles. However, since a profile feature was added, you can see the men who have chosen to make their profiles public. So, as long as you’re only talking about men who have made their profiles public, they can be viewed regardless of their class. That said, many genuinely good men keep their profiles private. And since much of the content is written by the men themselves, it may be no more reliable as information than what you find on an app. Still, you can sometimes get a sense of someone’s personality from the way they write, so their profile can provide clues for figuring out what kind of person they are.

You can’t. You can only view the profiles of men who have made their profiles public.
