> I thought of this a number of months ago, and I wonder, if server softwares would be somehow able to stop fetching posts for a dead account that lingers (until they log in) it would probably save quite a bit of resources (disk/ram/cpu), and it would also probably help with reducing overall network load...

I don't think it's much of a deal unless they have overlap with other ones. Being able to expire/refetch objects would be massive, though. This is part of Revolver's point, pieces can be discarded as long as there are enough copies of them, so some of the nodes keep *everything*.

Anyway, the rest of it, I think probabilistic per-user spam filters are the way to go.
