Telegraph today: "A senior judge has ordered Wikipedia, the online encyclopedia, to disclose the identity of one of its contributors after a mother and her young child pleaded for help in identifying an alleged blackmailer."

Worth noting what is at [[wmf:Privacy policy#Access to and release of personally identifiable information]]:
"Release: Policy on Release of Data
It is the policy of Wikimedia that personally identifiable data collected in the server logs, or through records in the database via the CheckUser feature, or through other non-publicly-available methods, may be released by Wikimedia volunteers or staff, in any of the following situations:
1. In response to a valid subpoena or other compulsory request from law enforcement,"
etc. While the Telegraph may possibly be correct that this is the first time for a British court to make such an order, I doubt this is the first instance of that clause being invoked.
