I noticed that when an album is set to a higher setting that G, the photos inside that album will not respect this setting as they will be shown in:

/albums-home (as their thumbnails)

/albums-popular (as their thumbnails)

/albums-top (as their thumbnails)

/albums-popular-media (displays the image regardless of the albums content filter setting)

/albums-top-media (displays the image regardless of the albums content filter setting)

I first noticed this when I was browsing my site an unauthenticated member where I could still see the images/thumbnails on the listed pages, but when I click into the image to see the context page, it will give a page not found as if the content never existed, so at least that works.

However, the fact remains that my site has two content filters (SFW) and (NSFW), when an album is set to NSFW and a member only has SFW enabled, the NSFW images within an album are still exposed to the user. Which means that anyone browsing the site that is not currently logged in are also getting exposed to the NSFW content.
