Twitter Card Whitelisted - but the notice about the media featuring "sensitive content" appears. There's nothing objectionable about the link

[SlugBooks]

Any twitter user who hasn’t opted in to seeing “sensitive content” is able to click “view summary” link, but the “We can’t show you everything!” message appears, telling users that the summary may contain photos/videos with sensitive content. There’s nothing sensitive about the content, we’re just providing information about the site, with an icon. Any ideas how to get past this block? Cards are virtually useless for as long as this block is here. Thanks in advance.

Here’s a specific instance of this occurring: https://twitter.com/stasiagrace/status/314795828235608064

mine does the same thing. except when i tweet pictures it blocks it from being seen until you click on “view media”. i went in the settings to change this but it still blocks all my pictures.
