Tweets indicated that there were 4 images of nude and semi-nude adults. Probably fits the definition of pornography.
Do we know who/what downloaded it?
Do we know if anyone viewed any or all of those images?
No, we don't.
Nude images does not equate to porn. There’s plenty of nudity in the art world, naturalist lifestyle and tons of nude pictures in museums. That’s not porn. IMO) to be deem as porn, the images would have to depict a sexual act.
