Does it really matter to you that said these things
outside wikipedia?
Yes. If for no other reason than the issue that requiring people to read
through Stormfront pages to review Wikipedian administrative decisions is
not a good thing.
But even if he had called someone a "vampire rodent" (wtf?) etc. inside
Wikipedia I still don't think an immediate permanent ban would have been
the right remedy.
