There are two issues at stake here: what we (as a community) should do about the present situation, and what we should do about future posts that are found to be plagiarised. I was trying to generalize the discussion and propose a set of actions that could be described in the site FAQs and applied to future posts.
Not in one fell swoop by an act of the god's - but bit by bit by the community as a whole, as we demonstate to them that we simply will not tolerate this sort of behaviour.
I agree completely.
Your $0.02, and I raise you $0.02
