@lunarloony @aetataureate In the US it isn't true that all quoting without written permission is illegal, but "fair use" IS a huge gray area that courts decide very inconsistently on, so depending on your degree of risk tolerance... it may be easier to just not risk it, yeah.
The law has four criteria for whether something is fair use:
1. The nature of the re-use (non-commercial uses, or "transformative" re-use like parody *may* get more latitude)
2. The nature of the copyrighted work (factual stuff generally gets less protection than artistic/imaginative, stealing un-published work is really bad)
3. Amount *and* "substantiality" of the portion used (so if you're re-using the heart of someone's work, that's worse)
4. Effect on the market (are you directly competing or reducing the copyright holder's sales?)
@aetataureate @lunarloony Ah crud. I don't know how to respond to that. What you're saying is pretty different to what I've gotten from lawyers the few times I've had occasion to talk to them about it.
But getting proper legal permission is always going to be the safer option, and I don't want to be (further) obnoxious about it so... yeah. I'll work on that knee-jerk "hang on, hang on, you should check that you're not paying them tribute that they have no right to" reaction. Sorry about that.
