Hello,
the board of the verein has made a decision for this (see Jakob Voss eMail from Sun, 06 Aug 2006 19:34:12 +0200). There is no further place for discussion.
BTW: A "Person der Zeitgeschichte" can only be seen in very limitated borders. If you ask somebody on the street "Who is XXX" and he/she can says it right, then you can use this rule. So it's only for politicans, sportsmans, showmasters, famous managers etc, but not for admins of a internetproject.
Sincerly, DaB.
