It seems not even the studios themselves can discern between legitimate and pirate copies
Knowing if something on the internet is infringing or not isn't as clear cut as the media companies would have you believe. After all, there are plenty of cases of companies asking websites to remove content that they themselves put there in the first place.But one Indian movie studio took this to new extremes, by uploading a pirated version of one of its movies to the official YouTube channel.
The movie has since been taken down, but it's still a mystery how it got uploaded in the first place.
It may make sense for the studio to own a pirated copy of its movie, if only to know what the pirates are up to, but it's safe to assume that it had a legitimate copy lying around somewhere as well.
