Even to strict ruling german courts, there is no problem
accumulating and publishing data on persons, that is "easily
accessible for everyone" by conventinal means. E.g. looking up how
many entries a person has in the public phone book and reporting
the count (without the phone numbers) would not be objectable.
That said, I do not assume that giving the magnitude of edits would
be a general problem. Especially not for admins, who are by
understandable and publicly available and agreed-upon rules
required to have a certain 'reputation by numbers' of edits, etc.
and thus must have implicitly accepted the rules, when they
choose to go for a voting.
Imho it would be sufficient to state in the [[Wikipedia:Admin]]
pages, that admins are subject to some public scrutinity and
control which means ... etc. (don't run for a pubic office, if
you don't like the implications, including some pubic attention
to your person)
Btw. German law has a notable exception (somewhat wider than
anglo-saxon, or EU understanding of the same) in that, what they
call "eine Person der Zeitgeschichte" - a person of contemporary
history - has considerably less rights to privacy than others.
That means, when you are in a public office, or run for one, or
are a well known actor, artits, tv-personality, trade unionist,
lobbyist, economic leader, scholar, author, etc. you cannot
prevent media reporting on you. You can demand truthfullness,
fairness, and to some extent decency, but you cannot e.g. (as every
nobody can) control which photographs they use, provided they
where taken on public ground, in public, or at a press-covered
appearance, etc.
In a lesser extend, the same idea could imho be applied to admins,
as far as their role as admins is concerned, and the data directly
related to, or describing, their work as admins.
Of course such ideas need to be laid down, discussed in the
various communities, and accepted. I assume that some diversity
will arise from that process. I think the international
foundation can and should point to the need and somehow collect
pointers to the individual rule sets a they become available, and
possibly destill some very basic principles from them and publish
these in simple sentences, but the foundation cannot determine the
rules - neither do they have the man power nor the knowledge, and
it's not their job. A need may arise to moderate needs or ideas
of various communities, when compatibility is questionable, so as
to find a workable overall solution. This might be done, or
initiated / coordinated by the foundation, details and fine print
likely to be treated by a specially appointed international expert
group, though.
My opinion (tm).
