My Noahide female friend has taken on modest attire, so as not to be a stumbling block. There are still pictures of her on friends' social media, in many of these she is dressed immodestly.
My questions are: Is there a source as to whether or not modesty (as it applies to lifnei iver) applies to non-Jewish women?
Does my friend have an obligation to get all these photos taken down, does she make a sin if someone sins as a result of her photos even if she is not the one hosting them?
Does she circumvent the issue if she converts, because she is a new person, or does she still get any new sins made if someone sees those photos?
Thank you everyone, I apologize if my question is longwinded or improperly formatted, I'm new here :)
