Especially when the images are scraped off the
CC-BY and CC-BY-SA Flickr
streams.
That was something I noticed the other day. An anon replaced the
infobox image on Veganism with a close-up shot of a woman's genitals
and a vibrator. I looked to see who had uploaded it and it said Flickr
upload bot. So is there a bot that uploads all cc images from Flickr
indiscriminately?
