Ah but you switched now from "I don't think people do this" to "people shouldn't do this". You're right about the latter but wrong about the former.

Yes, contrary to popular belief, even I am affected by context and change what I converse about as the discussions topic and context drift, this is called having a conversation.

I'll stand by that I think most Arch Linux users, extrapolated from the people I know also run it, review at least the domain/GitHub organization for random AUR packages, and all of them are aware of what the AUR actually is, and is for.

I don't think most people here on HN who are clearly misunderstanding what the AUR is, are actually Arch users, or if they are, they haven't read the header that been visible since forever on the AUR.
