The signal to noise ratio is probably pretty low, after passing the automated filters that get rid of most of the garbage. Most of this work is done by software. By the time it gets to the analysts who are making the database queries, they can pretty easily find what's useful for locking up political dissidents, murdering people with drones, etc without having to sift through a bunch of selfies and comments about Dancing with the Stars.
