if Clippy and QuirinusQuirrel were sock puppets of regular users (I think Quirrell is, but not Clippy)

Clippy is too.

If AK is a sock puppet, then yeah, it's something morally questionable the admins should deal with.

Weren't you just telling me that it is morally wrong for the admins to even look at the IP addresses?

But I wouldn't extend that to all sock puppets.

When it comes to well behaved sockpuppetts "Don't ask, don't tell" seems to work.
