Not the profiles themselves, that I am am aware of. If they have flagged their post as sensitive content, or Amethyst has done so, you can hide sensitive content temporarily, which will just hide the posts that contain it.

Yep, no full profile hiding yet. Though it could be possible to mark the entire profile as content sensitive.
Some profiles, like mine, that would certainly be fair, but others post a variety of content, not all of which is sensitive. So as long as that could be something the user posting content has control over, I don't see a problem with it.
