An equally important part is to refrain from doing it when you think the other part would be gravely offended. As Martin explained, he was paying homage to Zed. Instead of trying to understand the reasons someone would like to homage him, Zed insulted Martin.
When I ask someone to take down a plagiarized version of something I wrote (it happens) I usually point out I do not license the material on my site. I don't call people names not I insult them - I just point out they shouldn't do it and urge them to take the content down because it's not fine with me they reuse it. Even that is rare - I am usually happy with adequate attribution.
I can't understand why someone talented as Zed feels a need to insult people. But that's me and I am not like him.
2- if you don't get an answer, assume the subject is not that important to the person you asked
3- Do it
4- If person who ignored you denies you permission retroactively, comply
5- Complain when the person who ignored you and then denied you permission to do what you already did, which you promptly removed from public access, also insults you for no reason beyond not getting his attention in the first place.
