That's anthropomorphizing. ...

No, it's expressing the paperclip maximizer's state in ways that make sense to readers here. If you were to express the concept of being "bothered" in a way stripped of all anthropomorphic predicates, you would get something like "X is bothered by Y iff X has devoted significant cognitive resources to altering Y". And this accurately describes how paperclip maximizers respond to new threats to paperclips. (So I've heard.)

It also depends on how the utility function relates to time. It it's focused on end-of-universe paperclips, It might not care at all about melting paperclips, because it can recycle the metal later. (It would care more about the wasted energy!)

I don't follow. Wasted energy is wasted paperclips.

If it cares about paperclip-seconds then it WOULD view such tactics as a bonus, perhaps feigning panic and granting token concessions to get you to 'ransom' a billion times as many paperclips, and then pleading for time to satisfy your demands.

Okay, that's a decent point. Usually, such a direct "time value of paperclips" doesn't come up, but if someone were to make such a offer, that might be convincing: 1 billion paperclips held "out of use" as ransom may be better than a guaranteed paperclip now.

Getting something analogous to threatening torture depends on a more precise understanding of what the paperclipper wants. ...

Good examples. Similarly, a paperclip maximizer could, hypothetically, make a human-like mockup that just repetitively asks for help on how to create a table of contents in Word.
