@mangeurdenuage @gentoobro @hj @lanodan Yeah, but bots were obvious before, and again, CARNIVORE, right? It was keywords. When the NSA made that list of people accessing scary materials, it was based entirely on domains: people visiting the sites for the LKML and 2600 ended up on the watchlist. Manual review of lists of keywords: you get a lot of false positives and false negatives and it's a lot of work to build the lists.
