Has there been any discussion on this matter? If a user is being disruptive
on a wiki he or she will eventually end up getting blocked for it. If the
same user decides to continue this disruption he was blocked for on other
wikis, particularly sister projects, commons, meta and etc how should he or
she be treated.
I know every wiki is independent. But letting a disruptive user become the
source of agony on many wikis seems like a problematic thing to do.
