QUOTE
Posting another person's personal information (legal name, date of birth,
social security number, home or workplace address, telephone number, email
address, or other contact information, regardless of whether or not the
information is actually correct) is harassment, unless that editor
voluntarily provides or links to such information himself or herself. This
is because it places the other person at unjustified and uninvited risk of
harm in "the real world" or other media. This applies whether or not the
person whose personal information is being revealed is a Wikipedia editor.
It also applies in the case of editors who have requested a change in
username, but whose old signatures can still be found in archives.

I can tell you all with firm authority that this policy is not followed in block logs of suspected sockpuppets that have not voluntarily provided information or links to such information about his or her legal name. The blocking admin simply appends the legal name to the block summary, even on suspicion that it may only be someone "impersonating" the outted person.
It's a disgrace.
E-mail to OTRS produces a reply that OTRS does not have the technical capability of overwriting the block log, but that "If you are happy for your mail to be public, please subscribe to the wikitech mailing list and post there."
So, if you're trying to quietly get your legal name off of a Wikipedia user block summary, just publish your concern on the public mailing list!
