This sounds odd to me, unless you connected to an Ethernet port behind a desk or somehow forced open a network closet… They also might not like it if you disconnected one of the public computers to use its cable/port; otherwise if this was an open and public port, you used it as designed and the librarian probably has watched too many Hollywood hacking movies. I have to admit, I never thought of this as a way to bypass the captive portal (sorta just assumed everyone going through the public network would have to hit it, kinda of the equivalent to having everyone sign a liability waiver).
With that said, I can see some institutions not liking connections that aren’t part of the more traditional/commercial networking (but it doesn’t sound like the library took issue with your traffic, just the librarian didn’t like the PHY link you chose to use). For the SMS thing (I haven’t seen that used in a while, you might be able to use some sort of burner number app if they don’t filter them).
The article isn’t talking about taking the end product, it is about North Korean’s involved with the movie’s production by providing low cost manual labor for animating or ‘drafting’ the images for the shows (and then presumably a portion of this income is fed into the state). They’re not supposed to be doing this, but have identified ways to get jobs passed to them via some sort of broker who allocated part of the work to them or gets their citizens placed using fake credentials.
I usually wear deodorant (which generally has an antiperspirant in it), but there are days when I don't/haven't; in this limited experience I've noticed I would generally smell worse if I haven't been active. It seems like being up and moving around and sweating from 'labor' rather than sitting and sweating (not sure how to word that) is less likely to significantly smell. With all that said, I do try to shower after the gym or when I return inside after working on significant outdoor projects.
P.S., another data point to consider is the individual's age, as hormone levels (generally tied to age) could also influence perspiration
Ticks are terrible; creepy just as little things that get on you, but then they also carry all sorts of diseases which really drives up the paranoia after every hike
