Yes, and the idea that they "don't look at it" is not really true either. Every piece of collected data is sifted by computer algorithms that look for key words, etc. If any are found, a flag is set. That qualifies as "looking at it" IMO. Now, the system probably produces so many flags that they still can't actually read all of them. If I had that problem, I would sort the flagged data into arrays so I could look for patterns. If the same person gets flagged a set number of times, or the flags show something like keyword X and keyword Y, then his stuff gets read by a real person. The problem with that is that the message content would have to be kept so it could be examined if needed. Simply stated, I do not believe only metadata is kept. It would be useless if it couldn't be put into context when something odd is detected.
