Our understanding of the truth of things we read online is a social construct. Whether or not Hunter Biden received an email isn’t something ordinary readers like us will ever know, having no direct access to any of the evidence. At best we can read accounts written by others and decide whether they seem plausible.

Even our understanding of Hunter Biden’s existence is a social construct to most of us, since we have never met him and never will. (It’s much easier to make the call on that one, though, based on pictures and it being undisputed.)
