And who's the judge? The examples you linked are all from monks of level 20+ and 5+ years of experience on this site. So there is good reason to trust them with the power to have a node reaped.

But they don't have the power, they only considered the node, then monks vote, then janitors execute

Monks can still view reaped nodes

What about all the monks that were typing up responses to the OP's node before they "deleted" it? It's just as uncool as unmarked edits.

In this case there weren't any, but the node can be unreaped at any time (or even considered for unreaping), and monks can still view reaped nodes

If replies arrive, the node can be unreaped (hey its got replies now unreap)

And it has been unreaped by a janitor, who also answered it, eight hour later ... so the janitor has ruled, and thats the ruling, and it stands

janitors rule :)
