Some of the "tells": The whole thing has a "Chick Tract" vibe to it (personal, relatable story but with oddly specific details segueing into actions you can take for the good of your soul/safety of your family). Most of the items are obviously and patently false to anyone with any kind of domain knowledge, but are phrased earnestly enough that someone who assumes the writer is acting in good faith may not realize this. For example, number 4 suggesting that Snow Crash, Cryptonomicon, Neuromancer, etc. are "hacking manuals" or number 5's conflation of Disk Operating System DOS with Denial Of Service DOS.
It would be great if by this point in time everyone who saw something like this would realize it was either in jest or bad faith, but I suspect that computer illiteracy--and the number of folks who would take this at face value--is far higher than most of us realize (then again, maybe I'm just being overly cynical. I hope so; that's the sort of thing that I'd love to be wrong about! ;-) )
