They Have Listings Still in the Theaters
Sometimes you can instantly spot the thieves simply by browsing the movies they're offering. When it comes to ambitious pirating sites, this is one of the most obvious giveaways, for a couple of reasons.
Pirate sites compete not only against law enforcement but against each other. In order to entice as many viewers as possible, they offer up the freshest blockbusters.
Major studios seldom allow websites to stream movies that are still in theaters (though that practice could be changing). So, if you see streaming titles that are still showing at your local matinee, you can bet that the site is more than a little shady. A few legit streaming sites, such as Netflix, will release a movie it has produced in the theaters at the same time as on its streaming platform, but in those cases, there wouldn't be a copyright infringement.
