It's linked to in the message, I don't know the context but my best guess is the image that was added is of a known celebrity or an underage person, but the context isn't clear from the thread to me, it could also just be that the person is topless (though nothing is visible) and the author has been proactive about making the program default to no nudity.

I'm also not sure the images there are the ones that the original author is upset about since it looks like a branch where images were hosted was deleted.
