I like how you break this down. I suspect the result is behavior that almost everybody will find polite and respectful.
It is very similar to my policy of being willing to share lyrics to a filk with other filkers in some private manner (like e-mail), but not to post it on the internet. If the author put it there, I'll share a link; if I don't have a link to a public sharing made by the author, I stick to private sharing.
I also approve of at least thinking about whether it is appropriate to link to the wayback if a person is trying to rewrite history for some unethical purpose (including gaslighting). I certainly wouldn't do it lightly! But sometimes when a person has a pattern of behavior that hurts people, it falls under the "if you don't want people to talk about you doing a thing, don't do it" rule. But the post in question would have to be pertinent, and fanfic generally isn't.
