Child abuse pictures/videos can still be shared or sold online easily without PII. Other exceptions are celebrities or the difficulty in identifying PII in text.
After acquiring Maktoob, Yahoo! killed dvd4arab, one of the biggest Arabic content forums with over a decade of content, everything from political and sports discussion to poetry to (unfortunately) links to pirated content.
They didn't offer a backup or anything of even the 99% of subforums which were not involved in any piracy related activities. Sad..I still miss the awesome friendly environment that existed there..
