I can't help but notice (and question) the similarity between this and Facebook's statement - both give a 1000 warrant range and a 1000 affected user range.
Scripted by the NSA? Shared legal advice? _Surely_ not just a coincidence?
The government will only allow NSL and FISA warrants to be acknowledged within ranges of 1000 requests.
Correct. This is an artifact of DOJ/NSA demands for secrecy, nothing more.
