It's not just quantitative, but qualitative. Quantitatively, we're seeing
about 2% breakage through lists or so. Qualitatively, there's nothing
that we can do to make that zero, and as a given user through a
given piece of list software, the quantity may be 100% (Y! groups
seems to be one of those). Will these cause cases to be opened with
IT? Sure seems like it to me. Do IT folks like new cases opened for
acceptable behavior? Not that I've ever seen, especially when they
don't have a way to resolve it.
