During the BBS days, when certain books that I'd heard about but had never seen in person started making it to the boards, my dot matrix printer printed like mad. All that online literature started disappearing when the Internet became easy to use, I think in part because nobody wanted to be tracked as having downloaded something like the Anarchist's Cookbook.
I suppose she can try and censor that stuff, but like censoring plans for a 3D printed firearm, good luck trying.
