Its all pretty irrelevant, though, isn't it? GFDL says they can reuse
it anyway as long as it still says its from Wikipedia and provides
access to the history of contributors. As it relates to user conduct -
its off-site and outside the purview of en.wiki to regulate, not to
mention its completely harmless (diverging from David's mostly
harmless) and not worth debating.
If anyone can point to any actual harm here (rather than vague notions
of impropriety) then its worth considering if its covered by our
policies, if there are technical solutions to prevent such a thing
from happening, etc. Otherwise, all smoke and no fire. (Before you
tell me, yes I know - smoke kills).
