I take your point, Matt, but I feel you ought to have discussed this with the blocking admin, rather than undoing the block. I would also argue that for a Wikipedian to draw up a list of other editors by their perceived ethnicity, and to post that list on a racist website, is highly provocative, and I don't see how it can be detached from his actions on Wikipedia.
It is a list of those belonging to a "Zionist cabal". That's not a statement of ethnicity. I personally find it more amusing than offensive but I understand that people can legitimately feel differently. Perhaps this action is worthy of a ban but I would have preferred a more formal procedure preceding it.
He wasn't blocked for being a member of [[Vanguard News Network]] or [[Stormfront]], but for his actions in encouraging anti-Semites and racists to target Jewish editors, and for encouraging them to violate policy by creating sockpuppets and using open proxies.
As far as I can see it was another poster who made that suggestion. User:Amalekite replied with this:
"Signing up for a Wikipedia account and editing articles under that account instead of editing anonymously will greatly reduce your chances of being banned. It's much harder for them to claim you're a "vandal" if you've been making valid contributions to Wikipedia regularly, and kicking off a registered user is a much bigger deal and requires more justification on their part than banning an anonymous user. Signing up for an account there is easy "
I don't see why we should have to wait until the disruption begins before blocking him. He tried to cause massive disruption: that he (appears to have) failed was simply down to the others' lack of response.
In a charitable interpretation he tried to recruit new editors who would agree with his POV on a particular issue within compliance of Wikipedia rules. I've tried that too - with much the same luck...
In my personal opinion, and assuming I have the facts right, the user in question should be unblocked again.
