The document estimates that between 3% and 11% of the Yahoo webcam imagery harvested by GCHQ contains "undesirable nudity". Discussing efforts to make the interface "safer to use", it noted that current "naïve" pornography detectors assessed the amount of flesh in any given shot, and so attracted lots of false positives by incorrectly tagging shots of people's faces as pornography.
So, if you have to hide something, show your private parts. Can we conclude this?
Reminds me of this story, the googling of which is now in my search history so I hope you're grateful.
"A US card cloner forced would-be gang members to take part in group sex sessions as part of an initiation ceremony designed to weed out undercover cops, according to a detective."
Statistically speaking, it is now very probable that the GCHQ has collected a huge collection of materials classified as "pornography" (as in, naked people showing themselves on webcams to each other, believing that this is a private session; apparently this is a thing). Again, statistically speaking, a significant percentage of this is likely to be classified as "child pornography" (as in, teenagers doing the above). Therefore, does it follow that GCHQ thinks of the children, and not in a good way?
Riiiight: "Oh don't worry, it's not as if the data was collected with such intent, so it's all right, no problem exists. Also, this data doesn't even exist, so there."
crude, but probably very true. just remember that confessions of a TSA agent blog. I can't imagine it would be any different (if not worse, because the people aren't actually present).
